THIRD ANNOUNCEMENT (2015 April 15th)

Introduction:
--------------

A series of biannual meetings have been held since 2003 June, in order to discuss what may be learnt about the late-stages of stellar evolution from the study of hot subdwarfs and related objects. The scientific rationale for this seventh meeting, along with titles of talks proposed by those who registered on or before April 15th, is presented below. Further details may found at

http://www.physics.ox.ac.uk/subdwarfs2015

where a registration form is obtained by selecting "Register".

Scientific Rationale:
-------------------------

Asteroseismic observations of red giants by the Kepler Satellite demonstrate the transfer of angular momentum from the core to the envelope, as evolution up the Red Giant Branch (RGB) proceeds. That angular momentum transfer has consequences for any subsequent envelope loss and, for example, the formation of extremely low-mass white dwarfs and hot subdwarfs. While the workshop will focus on hot subdwarfs and related objects, as with previous workshops in the series, a part of that focus must necessarily be red giant envelope loss. Because extremely low-mass white dwarfs are understood to form as a result of envelope loss on the RGB, well before the helium core is massive enough to burn helium, their study is equally important when it comes to understanding red giant envelope loss. The Scientific Organising Committee therefore proposes that this Seventh Workshop on Hot Subdwarfs and Related Objects be held to advance our understanding of the late stages of stellar evolution by including discussion on the connection between red giants and their stripped cores (hot subdwarf stars and helium white dwarfs).

Contributed Talks Proposed by Registered Participants (15/04/2015):
---------------------------------------------------------------------------------------

01) Merger Rate of Low-Mass White Dwarf Binaries
02) The Formation of EL CVn - Type Binaries
03) Confronting the "Extreme Planetary Systems" claimed around sdBVs
04) Common-Envelope Evolution for the Formation of sdB Binaries
05) On the Nature of the Secondary Star in AA Dor
06) Kepler Observations of KIC 2697388
07) The Coolest Extremely Low-Mass White Dwarf and an Astrophysical Conundrum
08) Stripped Red Giant Stars
09) Kepler Observations of sdB Pulsators -- New Diagnostics for Asteroseismology
10) Interesting Features in Kepler-Observed sdB Stars
11) The EREBOS Project - Studying the Influence of Substellar Objects on the Late Stages of Stellar Evolution
12) MESA Stellar Evolution Models of sdB Stars
13) The Long-Term Outcomes of White Dwarf Mergers: sdBs and RCBs
14) Testing Eccentricity Pumping Processes in Wide sdB Binaries with MESA

Registration and Accommodation:
------------------------------------------

If you intend to register and attend the conference, be aware that July is a busy holiday month in Oxford and competition for the available accommodation is to be expected. Please also note that the Registration Fee will be increased to 200 pounds on June 1st. Titles and abstracts of proposed oral contributions need to be submitted by June 22nd; for posters, these may be submitted as late as July 17th.

VISAS:
--------

Nationals from a few countries may need visas to enter the United Kingdom for the purpose of attending the meeting. Requirements may be checked at

http://www.gov.uk/check-uk-visa

and if a letter supporting a visa application is needed, please ask me (aelg@astro.ox.ac.uk) to provide it.

Social Activities:
---------------------

Two tours are planned during the conference. The first is a half-day visit to Blenheim Palace, the cost of which we hope to fund out of the Registration Fee on the basis that all delegates would wish to participate; whether or not this works will depend on numbers. Secondly, a full-day tour to Stonehenge and Salisbury Cathedral is proposed for the Saturday following the meeting (July 25th); a separate charge will need to be made for this which should be calculable in early July once numbers are known.

The Conference Dinner is planned for July 22nd (Wednesday) and during the following evening I am hosting a reception at the Royal Oak to mark my sixty-fifth birthday which will have passed about a month earlier. All conference participants and their guests are invited, as are colleagues from the local Sub-Department of Astrophysics. While I would not expect to buy drinks for everyone throughout the evening, I propose providing some drinks and a buffet meal. If you are coming to the Royal Oak on July 23rd and have special dietary requirements, please let me know.

I look forward to welcoming you to Oxford, and to a scientifically productive conference.

SECOND ANNOUNCEMENT (2015 January 28th):

On behalf of the Scientific and Local Organising Committees, I am pleased to confirm that the Seventh Meeting on Hot Subdwarfs and Related Objects will be held at the Department of Physics, University of Oxford, from 2015 July 19th to 2015 July 25th. While reviewing properties of hot subdwarfs and our understanding of them, as in earlier meetings, the Scientific Organising Committee (SOC) has resolved that the Seventh Meeting should also explore the evolutionary link with red giants in more detail. In particular, it is intended that red giant core-envelope coupling be considered along with the consequent angular momentum transfer. Implications for red giant evolution and loss of envelope at or near the Helium Flash, leading to the formation of hot subdwarfs, needs to be discussed. For further details please see http://www.physics.ox.ac.uk/subdwarfs2015 and in particular the "Science Programme" link http://www-astro.physics.ox.ac.uk/~aelg/SDOB7/programme-sketch.pdf given in the "Programme" page, where the SOC presents a skeleton of its intended science programme. Please use the SOC's skeleton programme as a guide when preparing titles and abstracts for contributed talks.

Registration remains open and payment of the fee (currently 150 pounds) provides your teas, coffees and lunches, as well as drinks and snacks at the Reception on July 19th. If you are staying for five nights from July 19th and need a single room, I would encourage you to take advantage of our block booking at Keble College. As Oxford tends to host a large number of tourists in July, I would also urge you not to unnecessarily delay arranging your accommodation; if we need to negotiate with Keble College for extra rooms, the sooner this is known the greater will be our chance of success.

I look forward to welcoming you to Oxford in a little under six months from now.

Best regards,
Tony
