Future of the General Catalogue of Variable Stars from the Experience of Recent Name-lists
Open Astronomy, 2021 We briefly outline the history of the General Catalogue of Variable Stars (GCVS) and the New Catalogue of Suspected Variable Stars (NSV catalogue). Recently, we have completed a revision of the NSV catalogue.

The ASAS-SN Catalog of Variable Stars X: Discovery of 116,000 New Variable Stars Using g-band Photometry [PDF]
Monthly notices of the Royal Astronomical Society, 2022 The All-Sky Automated Survey for Supernovae (ASAS-SN) is the first optical survey to monitor the entire sky, currently with a cadence of ≲ 24 hours down to g ≲ 18.5 mag. ASAS-SN has routinely operated since 2013, collecting ∼ 2,000 to over 7,500 epochs

Catching a star before explosion: the luminous blue variable progenitor of SN 2015bh [PDF]
Astronomy & Astrophysics, 2017 In this paper we analyse the pre-explosion spectrum of SN2015bh by performing radiative transfer simulations using the CMFGEN code. This object has attracted significant attention due to its remarkable similarity to SN2009ip in both its pre- and post ...

HD 66051, an eclipsing binary hosting a highly peculiar, HgMn-related star
Scientific Reports, 2017 HD 66051 is an eclipsing system with an orbital period of about 4.75 d that exhibits out-of-eclipse variability with the same period. New multicolour photometric observations confirm the longevity of the secondary variations, which we interpret as a ...

The pulsating variable star population in DDO210 [PDF]
, 2015 We have probed the pulsating variable star content of the isolated Local Group dwarf galaxy, DDO210 (Aquarius), using archival Advanced Camera for Surveys/$Hubble$ $Space$ $Telescope$ imaging in the F475W and F814W passbands.

Using APASS and 2GSS for studying variable stars
EPJ Web of Conferences, 2017 The AAVSO Photometric All-Sky Survey (APASS) provides calibrated magnitudes in the range 7 < V < 17 for the entire sky, in the BVugriZsY bandpasses. While primarily designed for 0.02 mag calibration, it provides photometry over a many-year baseline, and ...
