TESS observations of Cepheid stars: first light results
E. Plachy, A. Pál, A. Bódi +33
We present the first analysis of Cepheid stars observed by the TESS space mission in Sectors 1 to 5. Our sample consists of 25 pulsators: ten fundamental mode, three overtone and t…
Orbital and physical parameters of eclipsing binaries from the ASAS catalogue -- XI. CHIRON investigation of long-period binaries
M. Ratajczak, R. K. Pawłaszek, K. G. Hełminiak +8
We present the results of a spectroscopic campaign on eclipsing binaries with long orbital period (P = 20 - 75 d) carried out with the CHIRON spectrograph. Physical and orbital sol…
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…
Towards an automatic processing of CCD images with CPCS 2.0
Pawel Zielinski, Lukasz Wyrzykowski, Przemyslaw Mikolajczyk +2
We present a new automatic tool for time-domain astronomy - the Cambridge Photometric Calibration Server 2.0 - developed under OPTICON H2020 programme. It has been designed to resp…
TESS Asteroseismic Analysis of the Known Exoplanet Host Star HD 222076
Chen Jiang, Timothy R. Bedding, Keivan G. Stassun +24
The Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission aiming to search for exoplanets that transit bright stars. The high-quality photometric data of TESS a…
A survey for variable young stars with small telescopes: II -- Mapping a protoplanetary disk with stable structures at 0.15 AU
Jack J. Evitts, Dirk Froebrich, Aleks Scholz +57
The HOYS citizen science project conducts long term, multifilter, high cadence monitoring of large YSO samples with a wide variety of professional and amateur telescopes. We presen…
