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…
Radiative transfer modeling of Haumea's dust ring
Csilla Kalup, László Molnár, Csaba Kiss
Among the growing number of small body rings in the solar system, the ring of Haumea has a special status as it is likely suitable for direct imaging in the visible and submillimet…
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…
New theoretical instability regions, period-luminosity relations and masses for blue large-amplitude pulsators
Susmita Das, Daniel Jadlovský, László Molnár
Blue large-amplitude pulsators (BLAPs) are a recently discovered group of hot pulsating stars whose evolutionary status remains uncertain. Their supposed progenitors are either $\s…
A Buddy for Betelgeuse: Binarity as the Origin of the Long Secondary Period in Orionis
Jared A. Goldberg, Meridith Joyce, László Molnár
We predict the existence of Ori B, a low-mass companion orbiting Betelgeuse. This is motivated by the presence of a 2170-day Long Secondary Period (LSP) in Betelgeuse's lightcu…
