EC 10246-2707: a new eclipsing sdB + M dwarf binary⋆
(OUP, 2013)
We announce the discovery of a new eclipsing hot subdwarf B + M dwarf binary,
EC 10246-2707, and present multi-colour photometric and spectroscopic observations
of this system. Similar to other HW Vir-type binaries, the ...
Periodic variations in the O-C diagrams of five pulsation frequencies of the DB white dwarf EC 20058-5234
(American Physical Society, 2013)
Variations in the pulsation arrival time of five independent pulsation frequencies of the DB white dwarf
EC 20058−5234 individually imitate the effects of reflex motion induced by a planet or companion but are
inconsistent ...
Hot subdwarf stars in close-up view IV. Helium abundances and the 3He isotopic anomaly of subdwarf B stars
(EDP Sciences, 2013)
Atmospheric parameters and helium abundances of 44 bright subdwarf B stars have been determined. More than half of our sample
consists of newly discovered stars from the Edinburgh Cape survey. We showed that effective ...
The ongoing pursuit of R Coronae Borealis stars: the ASAS-3 survey strikes again
(EDP Sciences, 2013)
CONTEXT: R Coronae Borealis stars( RCBs) are rare, hydrogen-deficient, carbon rich super giant variable stars that are likely the evolved merger products of pairs of CO and He white dwarfs. Only 55 RCB stars have been found ...
The Edinburgh-Cape Blue Object Survey - III. Zone 2; galactic latitudes -30? > b > -40?
(Oxford University Press, 2013)
The Edinburgh–Cape Blue Object Survey seeks to identify point sources with an ultraviolet
excess. Results for zone 2 of the survey are presented here, covering that part of the South
Galactic Cap between 30◦ and 40◦ from ...
