Interferometric Images of the Starspot Evolution of Andromedae
Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +21
The evolution of starspots of the giant primaries of RS CVn systems is typically detected indirectly with photometric and spectroscopic monitoring. These observations suggest slowl…
HATPI Pre-Perihelion Time-series Photometry of the Interstellar Comet 3I/ATLAS
Joel D. Hartman, Gáspár Ã. Bakos, Andrés Jordán +10
HATPI is a recently commissioned time-domain facility at Las Campanas Observatory, Chile, that uses 64 wide-angle, 9.6 cm diameter lenses and back-illuminated CCDs, yielding a mosa…
TIC65910228b: A single-transit discovery of a massive long-period warm Jupiter with TESS
Felipe I. Rojas, Rafael Brahm, MatÃas I. Jones +27
Context. Warm Jupiters are excellent case studies for the investigation of giant planet internal structures and formation theories. However, the sample of long-period transiting gi…
Multiband neural network classification of ZTF light curves as LSST proxies
Tamás Szklenár, Attila Bódi, Róbert Szabó
In this project we use data obtained by Zwicky Transient Facility to develop and test a neural-network-based, multiband classification algorithm to classify periodic variable stars…
Magnetic activity on the young Sun: a case study of EK Draconis
A. Görgei, L. Kriskovics, K. Vida +8
Context. Young, solar analogue stars provide key insights into the early stages of stellar evolution, particularly in terms of magnetic activity and rotation. Their rapid rotation,…
Exploring Low-Amplitude Variability in First Overtone Cepheids with TESS
E. Plachy, H. Netzel, A. Bódi
Classical Cepheid stars that pulsate in the first overtone radial mode often exhibit additional periodicities at the millimagnitude level. Extensive studies of the OGLE data of the…
