SN 2026dix: a nearby, transitional Type IIb/Ib supernova consistent with a warm supergiant progenitor

Tamás Szalai, Schuyler D. Van Dyk, Dominik Bánhidi +20

Understanding the final evolution stages of (very) massive stars and their explosive outcomes, stripped-envelope supernovae (SESNe), represent a long-term challenge for astrophysic…

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…

Sub-second cadence structure of optical flares on AD Leo

B. Schmercz, B. Seli, K. Vida +4

Stellar flares are sudden brightenings caused by magnetic reconnection and are frequently observed on late-type stars. High-cadence photometry of flares provides valuable insights…

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,…

Short- and long-term variations of the high mass accretion rate classical T Tauri star DR Tau

Gabriella Zsidi, Ágnes Kóspál, Péter Ábrahám +20

Classical T Tauri stars are newly formed, low mass stars which may display both periodic and random variations in their brightness. The interaction between the star and its circums…

The 2023 outburst of the Gaia alerted EXor Gaia23bab

Zsófia Nagy, Ágnes Kóspál, Péter Ábrahám +33

Episodic accretion is a fundamental process in the build-up of the stellar mass. EX Lupi-type eruptive young stars (EXors) represent one of the main types of episodic accretion. We…
