Constraints on the physical properties of Type Ia supernovae from photometry

R. Konyves-Toth, J. Vinko, A. Ordasi +17

We present a photometric study of 17 Type Ia supernovae (SNe) based on multi-color (Bessell BVRI) data taken at Piszkesteto mountain station of Konkoly Observatory, Hungary between…

Magnetic activity of the young solar analogue V1358 Ori

L. Kriskovics, Zs. Kővári, K. Vida +3

Young, fast rotating single stars can show dramatically different magnetic signatures and levels of magnetic activity as compared with the Sun. While losing angular momentum due to…

Deriving photospheric parameters and elemental abundances for a sample of stars showing the FIP effect

Bálint Seli, Levente Kriskovics, Krisztián Vida

One puzzling question in solar physics is the difference between elemental abundances in the photosphere and the corona. Elements with low first ionization potential (FIP) can be o…

The Type II-P Supernova 2017eaw: from explosion to the nebular phase

Tamás Szalai, József Vinkó, Réka Könyves-Tóth +36

The nearby SN 2017eaw is a Type II-P (``plateau') supernova showing early-time, moderate CSM interaction. We present a comprehensive study of this SN including the analysis of high…

Surface magnetic activity of the fast-rotating G5-giant IN Comae, central star of the faint planetary nebula LoTr 5

Zs. Kővári, K. G. Strassmeier, K. Oláh +8

On the AGB, low to intermediate mass stars blow away their outer envelopes, forming planetary nebulae. Interaction between the planetary nebula and its central progenitor is poorly…

The weakening outburst of the young eruptive star V582 Aur

G. Zsidi, P. Ábrahám, J. A. Acosta-Pulido +17

V582 Aur is a pre-main sequence FU Orionis type eruptive star, which entered a brightness minimum in 2016 March due to changes in the line-of-sight extinction. Here, we present and…

The quest for stellar coronal mass ejections in late-type stars: I. Investigating Balmer-line asymmetries of single stars in Virtual Observatory data

Krisztián Vida, Martin Leitzinger, Levente Kriskovics +5

Flares and CMEs can have deleterious effects on their surroundings: they can erode atmospheres of orbiting planets over time and also have high importance in stellar evolution. Mos…
