Detailed asteroseismic modeling of RR Lyrae stars with non-radial modes
H. Netzel, L. Molnar, M. Joyce
Photometric observations from the last decade have revealed additional low-amplitude periodicities in many classical pulsators that are likely due to pulsations in non-radial modes…
Comment on the feasibility of carbon burning in Betelgeuse: a response to "The evolutionary stage of Betelgeuse inferred from its pulsation periods," arXiv:2306.00287
László Molnár, Meridith Joyce, Shing-Chi Leung
The recent pre-print by Saio et al. 2023 argues that the supergiant Betelgeuse is already undergoing carbon burning, based on the assumption that all of its light variations are ca…
Frequency analysis of the first-overtone RR Lyrae stars based on the Extended Aperture Photometry from the K2 data
H. Netzel, L. Molnar, E. Plachy +1
Additional low-amplitude signals are observed in many RR Lyrae stars, beside the pulsations in radial modes. The most common ones are short-period signals forming a period ratio of…
Gaia Data Release 3. Summary of the variability processing and analysis

Context. Gaia has been in operations since 2014. The third Gaia data release expands from the early data release (EDR3) in 2020 by providing 34 months of multi-epoch observations t…
HD344787: a true Polaris analogue?
V. Ripepi, G. Catanzaro, L. Molnár +10
Classical Cepheids (DCEPs) are the most important primary indicators for the extragalactic distance scale, but they are also important objects per se, allowing us to put constraint…
Gaia Early Data Release 3: The Galactic anticentre

We aim to demonstrate the scientific potential of the Gaia Early Data Release 3 (EDR3) for the study of the Milky Way structure and evolution. We used astrometric positions, proper…
A low-luminosity core-collapse supernova very similar to SN 2005cs
Zoltán Jäger, József Vinkó, Barna I. Bíró +5
We present observations and analysis of PSN J17292918+7542390, a low-luminosity Type II-P supernova (LL SN IIP). The observed sample of such events is still low, and their nature i…
Light curves of ten Centaurs from K2 measurements
G. Marton, Cs. Kiss, L. Molnár +12
Here we present the results of visible range light curve observations of ten Centaurs using the Kepler Space Telescope in the framework of the K2 mission. Well defined periodic lig…
Rotational properties of Hilda asteroids observed by the K2 mission
Gyula M. Szabó, Csaba Kiss, Róbert Szakáts +7
Hilda asteroids orbit at the outer edge, or just outside of the Main Belt, occupying the 2:3 mean motion resonance with Jupiter. It is known that the group shows a mixed taxonomy t…
Solar System objects observed with TESS -- First data release: bright main-belt and Trojan asteroids from the Southern Survey
András Pál, Róbert Szakáts, Csaba Kiss +10
Compared with previous space-borne surveys, the Transiting Exoplanet Survey Satellite (TESS) provides a unique and new approach to observe Solar System objects. While its primary m…
X-ray Observations of the Peculiar Cepheid V473 Lyr Identify A Low-Mass Companion
Nancy Remage Evans, Ignazio Pillitteri, Laszlo Molnar +17
V473 Lyr is a classical Cepheid which is unique in having substantial amplitude variations with a period of approximately 3.3 years, thought to be similar to the Blazhko variations…
Extended Aperture Photometry of K2 RR Lyrae stars
Emese Plachy, László Molnár, Attila Bódi +6
The \textit{Kepler} space telescope observed thousands of RR Lyrae stars in the K2 mission. In this paper we present our photometric solutions using extended apertures in order to…
