Search of Short-Period Pulsating Variables(I) [PDF]
Journal of Astronomy and Space Sciences, 1996 CCD differential photometry was carried out for seven stars in the "New Catalogue of Suspected Variable Stars" in order to discover new short-period pulsating variables such as low and high amplitude δ Scuti stars and RR Lyrae stars.

The Astrophysical Journal Supplement SeriesUtilizing Zwicky Transient Facility (ZTF) data and existing RR Lyrae stars (RRLs) catalogs, this study achieves the first calibration of the P − ϕ _31 − R _21 − [Fe/H] and P − ϕ _31 − A _2 − A _1 − [Fe/H] relations in the ZTF photometric system for RRab ...

B V Photometry of RR Lyrae Variables in M15 [PDF]
Symposium - International Astronomical Union, 1984 New BV photographic photometry for 56 RR Lyrae variables in M15, combined with original measures by Sandage, Katem and Sandage (1981), yield data of improved precision which enable a rediscussion of the RR Lyrae characteristics and Oosterhoff problem.

Pulsating stars in the VMC survey
EPJ Web of Conferences, 2017 The VISTA survey of the Magellanic Clouds system (VMC) began observations in 2009 and since then, it has collected multi-epoch data at Ks and in addition multi-band data in Y and J for a wide range of stellar populations across the Magellanic system ...

RR Lyrae Variables and Stellar Evolution in M 15 [PDF]
Symposium - International Astronomical Union, 1984 The O-C curves — widely used for investigating the period behaviour of variable stars — are generally constructed under the assumption that the period changes are linear in time. If it is indeed so, the main trend of the diagram should outline a positive or negative parabola and β values are determined to characterize the curvature of the parabolae, i ...

Benchmarking Differential Reddening in Front of Globular Clusters
The Astronomical JournalInterstellar extinction is a major obstacle in determining accurate stellar parameters from photometry near the Galactic disk. It is especially true for globular clusters at low galactic latitudes, which suffer from significant amounts of spatially ...
