DOI: 10.1088/1674-4527/20/6/94
Abstract: RR Lyrae stars, a well-known type of pulsating variable stars, have been known about for more than a century. A large amount of photometric data on RR Lyrae stars has been accumulated by space- and… read more here.

DOI: 10.1093/mnras/staa1676
Abstract: RR Lyrae stars are an important and widely used tracer of the most ancient populations of our Galaxy, mainly due to their standard candle nature. The availability of large scale surveys of variable stars is… read more here.

DOI: 10.1093/mnras/stab005
Abstract: We present the results of a multi-component kinematic model of a large sample of RR Lyrae detected by $Gaia$. By imposing a four-fold symmetry and employing $Gaia$ proper motions, we are able to infer the… read more here.

DOI: 10.1093/mnras/stw3286
Abstract: Single star evolution does not allow extremely low-mass stars to cross the classical instability strip (IS) during the Hubble time. However, within binary evolution framework low-mass stars can appear inside the IS once the mass… read more here.

DOI: 10.1093/mnras/stx2819
Abstract: We exploit the first Gaia data release to study the properties of the Galactic stellar halo as traced by RR Lyrae. We demonstrate that it is possible to select a pure sample of RR Lyrae… read more here.
