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…
Estimation of the detected background by the future gamma-ray transient mission CAMELOT
J. Ripa, G. Galgóczi, N. Werner +18
This study presents a background estimation for the Cubesats Applied for MEasuring and LOcalising Transients (CAMELOT), which is a proposed fleet of nanosatellites for the all-sky…
Periodicities of the RV Tau-type pulsating star DF Cygni: a combination of Kepler data with ground-based observations
A. Bódi, K. Szatmáry, L. L. Kiss
The RV Tauri stars constitute a small group of classical pulsating stars with some dozen known members in the Milky Way. The light variation is caused predominantly by pulsations,…
LAMOST observations in the Kepler field. Database of low-resolution spectra
P. De Cat, J. N. Fu, A. B. Ren +34
The nearly continuous light curves with micromagnitude precision provided by the space mission Kepler are revolutionising our view of pulsating stars. They have revealed a vast sea…
Medium-resolution echelle spectroscopy of pulsating variables and exoplanet host stars with sub-meter telescopes
J. Kovács, B. Csák, B. Cseh +5
Here we present two of our interesting results obtained over the last 18 months from spectroscopic monitoring of binary pulsating stars and exoplanet host stars. Our investigations…
Subtle flickering in Cepheids
N. R. Evans, R. Szabo, L. Szabados +5
Fundamental mode classical Cepheids have light curves which repeat accurately enough that we can watch them evolve (change period). The new level of accuracy and quantity of data w…
Testing SNe Ia distance measurement methods with SN 2011fe
J. Vinko, K. Sarneczky, K. Takats +17
The nearby, bright, almost completely unreddened Type Ia supernova 2011fe in M101 provides a unique opportunity to test both the precision and the accuracy of the extragalactic dis…
Period and light curve fluctuations of the Kepler Cepheid V1154 Cyg
A. Derekas, Gy. M. Szabo, L. Berdnikov +11
We present a detailed period analysis of the bright Cepheid-type variable star V1154 Cygni (V =9.1 mag, P~4.9 d) based on almost 600 days of continuous observations by the Kepler s…
Spin-orbit resonance, transit duration variation and possible secular perturbations in KOI-13
Gy. M. Szabó, A. Pál, A. Derekas +3
KOI-13 is the first known transiting system exhibiting light curve distortions due to gravity darkening of the rapidly rotating host star. In this paper we analyze publicly availab…
The Kepler characterization of the variability among A- and F-type stars. I. General overview
K. Uytterhoeven, A. Moya, A. Grigahcene +38
The Kepler spacecraft is providing time series of photometric data with micromagnitude precision for hundreds of A-F type stars. We present a first general characterization of the…
Cepheid investigations using the Kepler space telescope
R. Szabó, L. Szabados, C. -C. Ngeow +35
We report results of initial work done on selected candidate Cepheids to be observed with the Kepler space telescope. Prior to the launch 40 candidates were selected from previous…
Ground-based observations of Kepler asteroseismic targets
K. Uytterhoeven, R. Szabo, J. Southworth +42
We present the ground-based activities within the different working groups of the Kepler Asteroseismic Science Consortium (KASC). The activities aim at the systematic characterizat…
Limits on Transit Timing Variations in HAT-P-6 and WASP-1
Gy. M. Szabó, O. Haja, K. Szatmáry +2
We detected the transit of HAT-P-6b at HJD 2454698.3908 +/- 0.0011 and that of WASP-1b at HJD 2454774.3448 +/- 0.0023. The updated orbital periods of the planets are 3.852992 +/- 0…
