Connections between the cycle-to-cycle light curve and O-C variations of the non-Blazhko RR Lyrae stars
J. M. Benkő, A. Bódi, E. Plachy +1
It has long been known that if the durations of the consecutive cycles of a pulsating star vary randomly, the O-C diagram could show quasi-periodic/irregular variations, even thoug…
Search for binary-channel metal-rich RR~Lyrae candidates
Hedieh Abdollahi, László Molnár, Vázsony Varga
The existence of dynamically young and metal-rich RR Lyrae stars challenges conventional notions of these variable stars. One possible scenario for their formation and evolution is…
A theoretical framework for BL Her stars IV. New period-luminosity relations in the Rubin-LSST filters
Susmita Das, László Molnár, Róbert Szabó +5
We present new theoretical light curves in the Rubin-LSST filters for a fine grid of BL Her models computed using MESA-RSP. We also derive new theoretical period-luminosity (PL) an…
A theoretical framework for BL Her stars III. A case study: Robust light curve optimisation in the LMC
Susmita Das, László Molnár, Gábor B. Kovács +8
We carry out an extensive light curve comparison of BL Her stars using observations from Gaia DR3 and stellar pulsation models computed using MESA-RSP with the goal to obtain the b…
Matching seismic masses for RR Lyrae-type and oscillating red horizontal-branch stars in M4
László Molnár, Henryka Netzel, Madeline Howell +2
Globular clusters offer a powerful way to test the properties of stellar populations and the late stages of low-mass stellar evolution. In this paper we study oscillating giant sta…
Validation of the RR Lyrae period determination in the Pan-STARRS PS1 3 survey with K2
Adrienn Forró, László Molnár, Emese Plachy +2
The Pan-STARRS 3 survey has detected hundreds of thousands of variable stars thanks to its coverage and 4-year time span, even though the sampling of the light curves is relativ…
