Binary Stars in the Space Era
Astrophysics Conference at Keele Hall, Keele University, UK
Monday 30th June to Friday 4th July, 2025
Rationale
The study of binary stars is one of the oldest areas of astrophysics. Results from binary stars are fundamental to our understanding of how stars form and evolve, galactic stellar populations, chemical evolution, and the cosmological distance scale. Wide binaries allow us to probe the properties of normal stars, including direct measurements of their masses. Eclipsing binaries are the only stars whose masses and radii can be measured to high precision. Close binaries can be used to study the physics of mass transfer, mass loss, accretion discs and how stars evolve. Binary star evolution is critical to the formation of cataclysmic variables, novae, supernovae, X-ray binaries, millisecond pulsars, gamma-ray bursts and gravitational wave events. Planets are found in binary star systems in both S-type and P-type orbits.
We are now firmly in the space-photometry era, with observations of binary stars available from the WIRE, MOST, BRITE, CoRoT, Kepler, TESS and CHEOPS satellites. In the near future PLATO will offer another leap forward in the quality of photometric data, and binary stars will in turn provide crucial information for the interpretation of the many planetary systems it will find. What legacy of achievements can we attribute to the study of binary systems? What is the current state of this area of astrophysics? What problems are still to be solved? How can we further improve our understanding of normal stars? What new analyses are now possible with Kepler, TESS and CHEOPS data? What more will PLATO allow us to do? How should we prepare? The aim of this conference is to bring together observational and theoretical astrophysicists to critique the past, understand the present, and organise the future of binary star research.

Code of Conduct
We value the participation of everyone at this meeting and want all attendees to have an enjoyable and fulfilling experience. Accordingly, all attendees are expected to show respect and courtesy to other attendees and staff.
As such, Keele University will be a harassment-free environment for everyone, regardless of gender, sexual orientation, disability, physical appearance, body size, race, nationality, religion. We do not tolerate harassment of attendees in any form.
- Speakers give their time freely, many have travelled a considerable distance, some are very distinguished, some are early career scientists perhaps giving a presentation at this level for the first time, and all deserve a fair and encouraging hearing. Please try to be on time for the start of a session, or otherwise slip quietly into the lecture hall, refrain from loud conversations outside the doors, switch off mobile phones, and if you must use a laptop computer do so inconspicuously.
- Harassment includes offensive verbal comments related to gender, sexual orientation, disability, physical appearance, body size, race, religion, sexual images in public spaces, deliberate intimidation, stalking, following, harassing photography or recording, sustained disruption of talks or other events, inappropriate physical contact, and unwelcome sexual attention.
- All communication given by speakers, organisers and attendees should be appropriate for a professional audience including people of many different backgrounds. Sexual language, jokes and imagery is not appropriate for any event.
- Be kind to others. Do not insult or put down other attendees.
- Respect Keele University staff.
- Behave professionally. Remember that harassment and sexist, racist, or exclusionary jokes are not appropriate.
Participants asked to stop any harassing behaviour are expected to comply immediately. Attendees violating these rules may be asked to leave the event, without a refund of any charge that may have been levied.
Thank you for helping make this a welcoming, respectful space for all.
This is a modified version of the code of conduct from the Royal Astronomical Society and we are grateful to them for making it available.
Location
The conference will be held in room DH 0.51 of the Dorothy Hodgkin building on the campus of Keele University. The registration desk will in the foyer at the main entrance, posters will be in room DH 0.63, and lunches and drinks in room DH 0.08. Evening meals, the welcome barbecue and the conference dinner will be in the Salvin Room and Old Library at Keele Hall. A little information on Keele Hall can be found in its wikipedia entry.
Information on how to get to the campus of Keele University can be found on the university travel page and on the Keele Conferences travel page. The closest large airports are Manchester and Birmingham, both of which have rail links to the train stations at Crewe and Stoke-on-Trent.
Warning: the UK has just implemented an Electronic Travel Authorisation (ETA) scheme. Most conference attendees from outside the UK will need to obtain one of these (cost £10) or may be refused entry to the UK. Please check carefully whether this applies to you, and get your ETA if needed.
Local Information for conference attendees
Campus Delegate Information document provided by Keele Conferences.
Out of hours key collection map provided by Keele Conferences.
Please note that Keele Hall has become a cashless venue. Any payments (e.g. for alcoholic drinks) must be done by card.
A printable map of Keele campus can be found here. The local information document linked above has a map with the important buildings for the conference labelled.
Accommodation
Standard accommodation will be en-suite rooms in one of the student accommodation blocks on campus. It will provisionally be in Barnes Halls, and final confirmation will be provided once the number of rooms required for the conference is known. Please declare on the registration form if you need a disabled room. Our supplier needs this information in advance to ensure a suitable room can be provided.
Attendees can instead opt for the Courtyard Hotel By Marriott on campus (building 53 on the campus map). To take this option, please register for the conference attendance package (not the full package) and arrange your stay with the Marriott Hotel yourself.
A third alternative for accommodation is to stay in Newcastle-under-Lyme, which is a 15-minute bus ride away. We do not recommend this option as it is much less convenient, but make it available in case it is useful. The Travelodge hotel is close to the bus route (First Bus route 25).
People wishing to stay extra night(s) before or after the conference can book into the Marriott hotel. This is because the standard accommodation has been allocated only for the duration of the conference.

Posters
The poster boards are big enough for a single A0 poster in portrait format or an A1 poster in either portrait or landscape format. Posters can be affixed with drawing pins or Velcro pads, which will be provided. The poster boards will be erected on Monday morning and removed on Friday afternoon. Each poster will be numbered and allocated a board for the full week.
We will have poster pop-up sessions at the end of each afternoon where poster authors will have one slide and one minute to present their work. If you wish to take advantage of this opportunity, please submit a slide to spacebinarytalks@gmail.com by the day before your poster session at the latest. An email has been sent to all poster presenters with further details of this.
Registration
The conference will last from Monday evening to Friday lunchtime, to allow many attendees to fit the conference and travel within one working week. Accommodation and food will be provided within the cost of the registration fee.
Full package: £750. This includes conference registration, accommodation (four nights, Monday to Friday), opening reception buffet (Monday night), breakfast (Tuesday to Friday), lunch (Tuesday to Friday), dinner (Tuesday and Wednesday), the conference dinner (Thursday), and morning and afternoon refreshments.
Attendance package: £450. This is like the full package but without accommodation or breakfast.
Please fill out this form if you wish to present a poster. Please do so even if you already signed up to do so. We are doing a second form to ensure we have the numbers correct and thus do not run out of poster boards.
