VizieR Online Data Catalog: Granulations of red supergiants from ASAS-SN & iPTF (Ren+, 2020)
Abstract
The time-series data are taken from the All-Sky Automated Survey for SuperNovae (ASAS-SN) for red supergiants (RSGs) in the Large Magellanic Cloud (LMC) and SMC and the Intermediate Palomar Transient Factory (iPTF) survey for RSGs in M31.
The ASAS-SN consists of 24 telescopes all around the globe that observed variable objects in the SMC and LMC at a cadence of 4-5 days for approximately 1600 days (Shappee+ 2014, J/ApJ/788/48 ; Kochanek+ 2017PASP..129j4502K). The ASAS-SN has magnitude limits of g~18 and V~17.3 and photometric precision of 0.08mag at V~16. For M31, the iPTF survey monitored for about 2000 days in the g and R bands, reaching 20.5mag at a 5σ level. We adopted the RSG sample in our previous work (Ren+ 2019, J/ApJS/241/35), which contains 420 RSGs in M31. (3 data files).- Publication:
