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…

Predictions from -process AGB models of the isotopic variations of zirconium and neodymium for comparison to bulk meteorites

Maria Lugaro, Giulia C. Cinquegrana, Balázs Szányi +6

Bulk meteoritic data show isotopic variability of -neutron-capture (-process) origin in a several elements heavier than Fe. One peculiar feature is that the lighter -pr…

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…

Stellar Interpretation of Meteoritic Data and PLotting for Everyone (SIMPLE): Isotope Mixing Lines for Six Sets of Core-Collapse Supernova Models

Marco Pignatari, Mattias Ek, Georgy V. Makhatadze +15

Bulk meteorites and their inclusions exhibit, for many chemical elements, isotopic variability produced by nucleosynthetic events in stars and supernovae before the formation of th…

The Gothard Observatory Synthetic Stellar Photometry Database

József Kovács, Szabolcs Mészáros, Beáta Harmati +6

Context. In order to determine stellar luminosities and radii, it is necessary to know the total bolometric fluxes emitted by the stars, or equivalently the bolometric corrections…

NEO and imminent impactor discoveries from Hungary: recent results and lessons learnt

Norton O. Szabo, Krisztian Sarneczky, Laszlo L. Kiss +15

2022 EB5, 2023 CX1 and 2024 BX1: these are the three recent imminent impactor discoveries from the Piszkéstető Mountain Station of the Konkoly Observatory. They make up about one…
