Stefan Huemmerich, Klaus Bernhard
TL;DR
This study investigates the star GDS J0702414-023501, analyzing its infrared properties and variability, and proposes it as a new Mira variable candidate based on multi-wavelength data and light curve analysis.
Contribution
The paper identifies GDS J0702414-023501 as a new Mira star candidate through comprehensive infrared and variability analysis, expanding the catalog of potential RCB stars.
Findings
GDS J0702414-023501 shows large amplitude variability.
Infrared colors suggest it is a carbon star.
Proposed as a new Mira star candidate.
Abstract
2MASS J07024146-0235017 = GDS J0702414-023501 was included in the "Catalogue enriched with R CrB stars" on grounds of its near- and mid-infrared colours. The object, which corresponds to the carbon star IRAS 07001-0230 = CGCS 6197, has been found to exhibit large amplitude variability in its Bochum Galactic Disk Survey light curve. Taking into account all available data, GDS J0702414-023501 is here proposed as a new candidate Mira star.
