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…

SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss

Qian Zhai, Jujia Zhang, Xiaofeng Wang +51

We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…

Exploring giant barium stars: ratio and elemental abundances of carbon, nitrogen, and oxygen

M. P. Roriz, N. A. Drake, N. Holanda +4

Barium (Ba) stars belong to binary systems that underwent mass transfer events. As a consequence, their envelopes were enriched with material synthesized in the interiors of their…

SN 2023ixf in M101: physical parameters from bolometric light curve modeling

J. Vinko, Zs. R. Bodola, A. Godeny +25

We present new photometric observations of the core-collapse supernova SN 2023ixf occurred in M101, taken with the RC80 and BRC80 robotic telescopes in Hungary. The initial nickel…

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…

Ejecta masses in Type Ia Supernovae -- Implications for the Progenitor and the Explosion Scenario

Zsófia Bora, Réka Könyves-Tóth, József Vinkó +35

The progenitor system(s) as well as the explosion mechanism(s) of thermonuclear (Type Ia) supernovae are long-standing issues in astrophysics. Here we present ejecta masses and oth…

SN 2022oqm: A Bright and Multi-peaked Calcium-rich Transient

S. Karthik Yadavalli, V. Ashley Villar, Luca Izzo +60

We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multi-peaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kp…
