BVRIJHK photometry of RR Lyrae variables

Publications of the Astronomical Society of the Pacific, 1992
Contemporaneous BVRI and JHK photometry are given for the RR Lyrae variables SW And and TU UMa. Additional BVRI photometry is included for the variables TT Lyn and T Sex and two JHK points for UU Vir. These 331 observations supplement those already published in our series of observations of RR Lyrae variables and can be phase-locked to radial ...

Cepheids and RR Lyrae type variables

Astronomische Nachrichten, 2013
AbstractCurrent status and development prospects of Cepheid and RR Lyrae‐type variable‐star studies (photometry, radial velocity measurements, galactic structure and kinematics, and distance‐scale refinement) at the Sternberg Astronomical Institute are reported.

Companions to RR Lyrae Variables

Publications of the Astronomical Society of Australia, 1970
A powerful approach to the understanding of any group of stars is the study of any companion stars which can be shown to be physically connected. But RR Lyrae variables, in common with other members of Population II are deficient in physical pairs. Baize’s catalogue of variables with companions contains only one: CSV 1795 = ADS 9354 A. As far as can be

A newly discovered distant RR Lyrae variable

Publications of the Astronomical Society of the Pacific, 1986
A new variable has been found 38 arcmin from the center of the Draco galaxy. The light curve and distance modulus of this star suggest it is an RR Lyrae variable far out in the halo of the Galaxy. Magnitudes and a finding chart for this star are given. While farther away than the variables discovered by the Lick survey, it is not the farthest Galactic ...

The Red RR Lyrae Variable DK Velorum

Publications of the Astronomical Society of the Pacific, 1971
DK Vel appears to be a short-period, metal-rich variable, cooler than any other RH Lyrae star.

A possible new RR Lyrae variable star

Publications of the Astronomical Society of the Pacific, 1984
UBV observations and a light curve are presented for a new variable star, chosen to be a companion star for the very hot degenerate dwarf PG 1520 + 525, and these data are found to be consistent with the interpretation that the new variable is a halo RR Lyrae variable of Bailey's type 'c'.
