Abstract:
RR Lyrae stars are excellent tracers of the old population II due to
their period-luminosity (PL) and period-luminosity-metallicity (PLZ)
relations. While these relations have been investigated in detail in
many photometric bands, there are few comprehensive studies about them
in Sloan-like systems. We present PL and PLZ relations (as well as
their counterparts in Wesenheit magnitudes) in the Sloan-Pan-STARSS
gP1rP1iP1 bands obtained for Galactic RR Lyrae stars in the vincinity
of the Sun. The data used in this paper were collected with the
network of 40cm telescopes of the Las Cumbres Observatory, and
geometric parallaxes were adopted from Gaia Data Release 3. We derived
PL and PLZ relations separately for RRab and RRc-type stars, as well
as for the mixed population of RRab+RRc stars. To our knowledge, these
are the first PL and PLZ relations in the Sloan bands determined using
RR Lyrae stars in the Galactic field.
Description:
The light curves of 44 RRab and 9 RRc stars from the vincinity of the
Sun were obtained. The data were collected between 2021 August and
2022 July with 16 robotic 40 cm telescopes of the Las Cumbres
Observatory (LCO) Global Telescope Network. Images were taken with
3Kx2K STL-6303 cameras with the field of view of 29.2'x19.5' and pixel
scale of 0.571"/pix in three Sloan g'r'i' filters. Instrumental
magnitudes were calibrated to the ATLAS All-Sky Stellar Reference
Catalog version 2 (ATLAS-REFCAT2; Tonry et al., 2018ApJ...867..105T 2018ApJ...867..105T,
Cat. J/ApJ/867/105), which is in the Sloan-Pan-STARSS gP1rP1iP1 system
(Tonry et al., 2012ApJ...750...99T 2012ApJ...750...99T, Cat. J/ApJ/750/99).
