Variable Star Census in CoRoT "Eyes" [PDF]
arXiv, 2007 A complete catalogue of variable stars in the possible observing areas (``eyes'') of the CoRoT satellite is presented. All known data sources were cross-correlated and compiled confirming the variability of 81 stars formerly known as suspected variables.

, 2012 We have used deep V and R images acquired at the ESO Very Large Telescope to identify the optical companion to the binary pulsar PSR J0610-2100, one of the black-widow millisecond pulsars recently detected by the Fermi Gamma-ray Telescope in the Galactic

Variable stars in young open star cluster NGC 7380 [PDF]
, 2015 We present time series photometry of 57 variable stars in the cluster region NGC 7380. The association of these variable stars to the cluster NGC 7380 has been established on the basis of two colour diagrams and colour-magnitude diagrams. Seventeen stars are found to be main-sequence variables, which are mainly B type stars and are classified as slowly

Variability of Red Stars [PDF]
Nature, 1896 ACCORDING to a notice, which I found in NATURE'S “Astronomical Column” of November 14, 1895, my theory of the variability of red stars should demand, that the bright lines of hydrogen should be produced there at a low temperature and in a condition never tested by experiments.

The Gaia Parallax Discrepancy for the Cluster Pismis 19 and Separating δ Scutis from Cepheids
The Astrophysical JournalPre-Gaia distances for the open cluster Pismis 19 disagree with Gaia parallaxes. A Two Micron All Sky Survey (2MASS) JK _s red clump distance was therefore established for Pismis 19 (2.90 ± 0.15 kpc), which reaffirms that zero-point corrections for Gaia ...
