Stellar Forcing of (exo)Planetary Environments
Julián D. Alvarado-Gómez, Erika Palmerio, Manuel Güdel +13
The environments of exoplanets are fundamentally shaped by the magnetic activity of their host stars through radiative, plasma, and particle-driven processes. This article presents…
Long-term optical and near-infrared photometric evolution of SN 2019vxm, an interacting Type IIn supernova
Klára Lelkes, László Molnár, József Vinkó +12
The diversity of Type IIn supernovae is largely driven by the properties of the circumstellar material (CSM) they explode into. We examine the temporal evolution of SN 2019vxm, an…
Distance estimate to NGC 6951 from supernova siblings Type IIP SN 2020dpw and Type Ib SN 2021sjt
Réka Könyves-Tóth, Zsófia Bodola, Tamás Szalai +24
{Supernova (SN) siblings are powerful tools used to calibrate and improve distance measurement methods, and to make the systematic uncertainty to distances to their host galaxies c…
The Preliminary Mauve Science Programme: Science themes identified for the first year of operations
Mauve Science Collaboration, Marcel Agueros, Don Dixon +22
Mauve is a low-cost small satellite developed and operated by Blue Skies Space Ltd. The payload features a 13 cm telescope connected with a fibre that feeds into a UV-Vis spectrome…
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…
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…
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…
Stellar flares, superflares and coronal mass ejections -- entering the Big data era
Krisztián Vida, Zsolt Kővári, Martin Leitzinger +6
Flares, sometimes accompanied by coronal mass ejections (CMEs), are the result of sudden changes in the magnetic field of stars with high energy release through magnetic reconnecti…
NEOWISE-R Caught the Luminous SN 2023ixf in Messier 101
Schuyler D. Van Dyk, Tamas Szalai, Roc M. Cutri +16
The reactivated Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE-R) serendipitously caught the Type II supernova SN 2023ixf in Messier 101 on the rise, starting day 3…
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…
Abundant sub-micron grains revealed in newly discovered extreme debris discs
A. Moór, P. Ábrahám, K. Y. L. Su +7
Extreme debris discs (EDDs) are bright and warm circumstellar dusty structures around main sequence stars. They may represent the outcome of giant collisions occuring in the terres…
Flare stars in nearby Galactic open clusters based on {\it TESS} data
O. Maryeva, K. Bicz, C. Xia +3
The study is devoted to search for flare stars among confirmed members of Galactic open clusters using high-cadence photometry from {\it TESS} mission. We analyzed 957 high-cadence…
The Exotic Type Ic Broad-Lined Supernova SN 2018gep: Blurring the Line Between Supernovae and Fast Optical Transients
T. A. Pritchard, Katarzyna Bensch, Maryam Modjaz +28
In the last decade a number of rapidly evolving transients have been discovered that are not easily explained by traditional supernovae models. We present optical and UV data on on…
SN 2016coi/ASASSN-16fp: An example of residual helium in a type Ic supernova?
