Sometimes I explore some ideas to a sufficient depth that it seems worthwhile for me to archive the technical derivations even if the idea itself does not immediately produce a publishable resultThis page, which has a simple outline layout, provides links to these various pages of technical notes.
At our regularly scheduled astrophysics group meeting on Monday, 2 May 2011, Juhan Frank and I started debating the answer to the following question:  What should the photospheric radius be of the common envelope that surrounds a stably accreting, DWD binary?  That is, does an accreting DWD binary that is destined to be an AM CVn system, look like a single bloated star?  The various mathematical relations that we think are relevant to this question were sketched on the whiteboard in room 218 Johnston Hall (CCT)Here is a photo of that whiteboard discussion and derivation.

Locating the Photosphere of Stably Accreting White Dwarfs

At our regularly scheduled astrophysics group meeting on Monday, 2 May 2011, Juhan Frank and I started debating the answer to the following question: What should the photospheric radius be of the common envelope that surrounds a stably accreting, DWD binary? That is, does an accreting DWD binary that is destined to be an AM CVn system, look like a single bloated star? The various mathematical relations that we think are relevant to this question were sketched on the whiteboard in room 218 Johnston Hall (CCT). Here is a photo of that whiteboard discussion and derivation.
