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…
The FU Ori outburst of PR Ori B
Carlos Contreras Pena, Zsofia Nagy, Gregory Herczeg +42
We report the discovery of a nearby FU Ori-type outburst (FUor), PR Ori B, in the L1641 cluster of the Orion star-forming region. The high-amplitude variability was first identifie…
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…
The Enigma of Gaia18cjb: a Rare Hybrid of FUor and EXor?
Eleonora Fiorellino, Peter Abraham, Agnes Kospal +28
Context. Gaia18cjb is one of the Gaia-alerted eruptive young star candidates which has been experiencing a slow and strong brightening during the last 13 years, similar to some FU…
Three is the magic number -- distance measurement of NGC 3147 using SN 2021hpr and its siblings
Barnabas Barna, Andrea P. Nagy, Zsofia Bora +15
The nearby spiral galaxy NGC 3147 hosted three Type Ia supernovae (SNe Ia) in the past decades, which have been subjects of intense follow-up observations. Simultaneous analysis of…
Initial 56Ni Masses in Type Ia Supernovae
Zsófia Bora, József Vinkó, Réka Könyves-Tóth
We infer initial masses of the synthesized radioactive nickel-56 in a sample of recent Type Ia supernovae applying a new formalism introduced recently by Khatami & Kasen (2019). It…
A multi-epoch, multi-wavelength study of the classical FUor V1515 Cyg approaching quiescence
Zs. M. Szabó, Á. Kóspál, P. Ábrahám +28
Historically, FU Orionis-type stars are low-mass, pre-main sequence stars. The members of this class experience powerful accretion outbursts and remain in an enhanced accretion sta…
