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…
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…
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 p…
Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
Asteroid sizes determined with thermophysical model and stellar occultations
A. Choukroun, A. Marciniak, J. Ďurech +165
Context. The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability of…
Comparison of three different camera systems monitoring the meteor activity over Hungary in 2020-2023
Livia Deme, Krisztian Sarneczky, Antal Igaz +4
We present statistical analysis of visual meteor data taken with networks of meteor cameras operating in Hungary between 2020 and 2023. We use three different camera systems: a set…
Searching for Supernovae in HETDEX Data Release 3
J. Vinko, B. P. Thomas, J. C. Wheeler +11
We have extracted 636 spectra taken at the positions of 583 transient sources from the third Data Release of the Hobby-Eberly Telescope Dark Energy eXperiment (HETDEX). The transie…
Mid-infrared time-domain study of recent dust production events in the extreme debris disc of TYC 4209-1322-1
A. Moór, P. Ábrahám, Á. Kóspál +23
Extreme debris discs are characterized by unusually strong mid-infrared excess emission, which often proves to be variable. The warm dust in these discs is of transient nature and…
SN2017jgh - A high-cadence complete shock cooling lightcurve of a SN IIb with the Kepler telescope
P. Armstrong, B. E. Tucker, A. Rest +69
SN 2017jgh is a type IIb supernova discovered by Pan-STARRS during the C16/C17 campaigns of the Kepler/K2 mission. Here we present the Kepler/K2 and ground based observations of SN…
SN 2018zd: An Unusual Stellar Explosion as Part of the Diverse Type II Supernova Landscape
Jujia Zhang, Xiaofeng Wang, Jozsef Vinko +29
We present extensive observations of SN 2018zd covering the first \,d after the explosion. This SN shows a possible shock-breakout signal \,hr after the explosion…
Gaia 18dvy: a new FUor in the Cygnus OB3 association
E. Szegedi-Elek, P. Ábrahám, L. Wyrzykowski +59
We present optical-infrared photometric and spectroscopic observations of Gaia18dvy, located in the Cygnus OB3 association at a distance of 1.88 kpc. The object was noted by the Ga…
Light curves of ten Centaurs from K2 measurements
G. Marton, Cs. Kiss, L. Molnár +12
Here we present the results of visible range light curve observations of ten Centaurs using the Kepler Space Telescope in the framework of the K2 mission. Well defined periodic lig…
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…
K2 Observations of SN 2018oh Reveal a Two-Component Rising Light Curve for a Type Ia Supernova
G. Dimitriadis, R. J. Foley, A. Rest +145
We present an exquisite, 30-min cadence Kepler (K2) light curve of the Type Ia supernova (SN Ia) 2018oh (ASASSN-18bt), starting weeks before explosion, covering the moment of explo…
Absolute Distances to Nearby Type Ia Supernovae via Light Curve Fitting Methods
J. Vinkó, A. Ordasi, T. Szalai +22
We present a comparative study of absolute distances to a sample of very nearby, bright Type Ia supernovae (SNe) derived from high cadence, high signal-to-noise, multi-band photome…
