VizieR Online Data Catalog: Periodic dwarf carbon stars from ZTF & Gaia (Roulston+, 2021)

We compiled a list of all dwarf carbons (dCs) from the current literature. The largest contributor (747 dCs, 79%) is the Green (2013, J/ApJ/765/12) sample of carbon stars from the SDSS. We also selected a smaller number of dCs from Si+ (2014, J/other/SCPMA/57.176), who found 96 new dCs using a label propagation algorithm from SDSS DR8, and from Li+ (2018, J/ApJS/234/31), who selected carbon stars from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope survey (LAMOST) using a machine-learning approach. Our resulting final sample consists of 944 dCs. With our compiled sample, to ensure that any periodic candidate was indeed a dC star, we used Gaia EDR3 parallaxes, proper motions, and distances.

Using our list of dCs, we cross-matched our sample to the ZTF DR5. The final sample of light curves resulted in 833 dCs with ZTF g light curves, 867 dCs with ZTF r light curves, and 554 dCs with ZTF i light curves. Table 2 contains the properties for this final periodic dC sample.
