Toward more accurate RR Lyrae metallicities
Geza Kovacs, Johanna Jurcsik
By using a large sample of published spectroscopic iron abundances, we point out the importance of gravity correction in deriving more accurate metal abundances for RR Lyrae stars.…
A Study of Stellar Spins in 15 Open Clusters
Brian F. Healy, P. R. McCullough, Kevin C. Schlaufman +1
We analyze spectroscopic and photometric data to determine the projected inclinations of stars in 11 open clusters, placing constraints on the spin-axis distributions of six cluste…
Near infrared and optical emission of WASP-5 b
G. Kovacs, I. Dekany, B. Karamiqucham +4
CONTEXT: Thermal emission from extrasolar planets makes it possible to study important physical processes in their atmospheres and derive more precise orbital elements. AIMS: By us…
Bright single-mode RR Lyrae stars: matching Gaia EDR3 with pulsation and evolutionary models
Geza Kovacs, Behrooz Karamiqucham
We combine observed metallicity, optical and infrared magnitudes with evolutionary and pulsation models to derive average luminosities for 156 single-mode RR Lyrae stars. These lum…
Probing galactic double-mode RR Lyrae stars against Gaia EDR3
Geza Kovacs, Behrooz Karamiqucham
Classical double-mode pulsators (RR Lyrae stars and delta Cepheids) are important for their simultaneous pulsation in low-order radial modes. This enables us to put stringent const…
More planetary candidates from K2 Campaign 5 by tran_k2
Geza Kovacs
CONTEXT. The exquisite precision of the space-based photometric surveys and the unavoidable presence of instrumental systematics and intrinsic stellar variability call for the deve…
