New R Coronae Borealis stars discovered in OGLE-III Galactic bulge fields from their mid- and near-infrared properties
Context. An R Coronae Borealis (RCB) star is a rare type of supergiant star that is increasingly suspected to be the evolved merger product of two white dwarfs. Lately, many RCBs have been found distributed in a thin disk structure embedded inside the Galactic bulge. This unexpectedly high density may provide additional insight into the nature and age of RCB stars. Aims. We apply and test a new technique to find RCB stars based on their particular infrared emission due to circumstellar shell....[Show more]
