Asteroseismology of the heartbeat star KIC 5006817
Merc, J.; Sánchez Arias, J. P.; Beck, P. G. +2 more
This paper summarizes the project work on asteroseismology at the ERASMUS+ GATE 2020 Summer school on space satellite data. The aim was to do a global asteroseismic analysis of KIC 5006817, and quantify its stellar properties using the high-quality, state of the art space missions data. We employed the aperture photometry to analyze the data from …
Flare stars in nearby Galactic open clusters based on TESS data
Baratella, M.; Vida, K.; Maryeva, O. +3 more
The study is devoted to search for flare stars among confirmed members of Galactic open clusters using high-cadence photometry from TESS mission. We analyzed 957 high-cadence light curves of members from 136 open clusters. As a result, 56 flare stars were found, among them 8 hot B-A type objects. Of all flares, 63 % were detected in sample of cool…
V355 And: a neglected detached binary in a multiple star system
Özkardeş, B.
The analysis of light curves (from TESS, ASAS--SN and KWS databases) of the eclipsing binary V355 And is presented for the first time. The O-C diagram was constructed using all available times of minimum light together with the ones determined in this study, and the revised ephemeris was obtained. The final photometric model describes V355 And as …
Improving light curve parameters of exoplanets based on TESS data
Parviainen, H.; Maliuk, A.; Vítková, M. +1 more
We revise parameters of four transiting hot Jupiter planets discovered by ground-based surveys. We use follow-up observations carried by TESS mission together with PyTransit software. Space telescopes like TESS provide better coverage and photometry precision than ground-based telescopes. PyTransit is fast and user-friendly exoplanet transit light…
Photometric and period analysis of the eclipsing binary system V2783 Ori
Bulut, İ.; Bulut, A.
In this study we performed the first detailed photometric and period analysis of the recently discovered eclipsing binary star V2783 Ori. The analysis of the light curve has shown that the system is in a detached configuration, with the orbital eccentricity e = 0.274 ± 0.008. The photometric mass ratio of V2783 Ori determined from the light curve …
The GATE summer school
Paunzen, E.; Skarka, M.; Janík, J. +1 more
The education activities in the form of short and condensed courses such as summer schools are essential parts of the educational process of every scientist. Here we briefly describe the program and the organization of the GATE summer school that was held in a form of virtual meeting between August 8 and 15 in Brno, Czech Republic.
