The quest for stable circumbinary companions to post-common envelope sdB eclipsing binaries Does the observational evidence support their existence?
D. Pulley, G. Faillace, D. Smith +2
Context. Period variations have been detected in a number of eclipsing close compact binary subdwarf B stars (sdBs) and these have often been interpreted as caused by circumbinary…
The eclipsing binary HS0705+6700 and the search for circumbinary objects
D. Pulley, G. Faillace, D. Smith +1
HS0705+6700 (also identified as V470 Cam) is a short period (2.3 h) post common envelope detached eclipsing sdB binary system which exhibits transit time variations (TTVs) of a cyc…
EL CVn-type binaries - Discovery of 17 helium white dwarf precursors in bright eclipsing binary star systems
P. F. L. Maxted, S. Bloemen, U. Heber +21
The star 1SWASP J024743.37-251549.2 was recently discovered to be a binary star in which an A-type dwarf star eclipses the remnant of a disrupted red giant star (WASP0247-25B). The…
Investigating the properties of the near contact binary system TW CrB
G. Faillace, C. Owen, D. Pulley +1
TW Coronae Borealis (TW CrB) is a binary system likely to be active showing evidence of starspots and a hotspot. We calculated a new ephemeris based on all available timings from 1…
