A new framework of multidimensional pulsating stellar envelopes I.: Properties of turbulent convection in static RR Lyrae envelope models with SPHERLS
Gábor B. Kovács, R. Szabó, J. Nuspl
Context. The one-dimensional treatment of turbulent convection had large successes until the early 2000s. However, the recent abundance and precision of observational data shows th…
The Heavy Element Enrichment History of the Universe from Neutron Star Mergers with Habitable Worlds Observatory
Eric Burns, Jennifer Andrews, Robert Szabo +23
Understanding where elements were formed has been a key goal in astrophysics for nearly a century, with answers involving cosmology, stellar burning, and cosmic explosions. Since 1…
Background exoplanet candidates in the original Kepler field
John Bienias, Robert Szabo
Context. During the primary Kepler mission, between 2009 and 2013, about 150,000 pre-selected targets were observed with a 29.42 minute-long cadence. However, a survey of backgroun…
On the incidence rate of RR Lyrae stars with non-radial modes
H. Netzel, V. Varga, R. Szabo +2
Over the recent years, additional low-amplitude non-radial modes were detected in many of the first-overtone RR Lyrae stars. These non-radial modes form a characteristic period rat…

We present the results of a systematic search for new rapidly oscillating Ap (roAp) stars using the 2-min cadence data collected by the Transiting Exoplanet Survey Satellite (TESS)…
TESS observations of Cepheid stars: first light results
E. Plachy, A. Pál, A. Bódi +33
We present the first analysis of Cepheid stars observed by the TESS space mission in Sectors 1 to 5. Our sample consists of 25 pulsators: ten fundamental mode, three overtone and t…
A modulated RRd star observed by K2
E. Plachy, P. Klagyivik, L. Molnár +1
We report the analysis of the double-mode RR Lyrae star EPIC 205209951, the first modulated RRd star observed from space. The amplitude and phase modulation are present in both mod…
The additional-mode garden of RR Lyrae stars
L. Molnár, E. Plachy, P. Klagyivik +6
Space-based photometric missions revealed a surprising abundance of millimagnitude-level additional modes in RR Lyrae stars. The modes that appear in the modulated fundamental-mode…

A. Derekas, E. Plachy, L. Molnar +8
We present a detailed analysis of the bright Cepheid-type variable star V1154 Cygni using 4 years of continuous observations by the Kepler space telescope. We detected 28 frequenci…
The heart of the swarm: K2 photometry and rotational characteristics of 56 Jovian Trojan asteroids
Gy. M. Szabó, A. Pál, Cs. Kiss +6
We present fully covered phased light curves for 56 Jovian Trojan asteroids as acquired by the K2 mission of the Kepler space telescope. This set of objects has been monitored duri…
Uninterrupted optical light curves of main-belt asteroids from the K2 Mission
R. Szabó, A. Pál, K. Sárneczky +6
Due to the failure of the second reaction wheel, a new mission was conceived for the otherwise healthy Kepler space telescope. In the course of the K2 Mission, the telescope is sta…

The CoRoT satellite supplied the scientific community with a huge data base of variable stars. Among them the RR Lyrae stars have intensively been discussed in numerous papers in t…
Metal-rich or misclassified? The case of four RR Lyrae stars
L. Molnár, Á. L. Juhász, E. Plachy +1
We analysed the light curve of four, apparently extremely metal-rich fundamental-mode RR Lyrae stars. We identified two stars, MT Tel and ASAS J091803-3022.6 as RRc (first-overtone…
