Towards the true number of flaring giant stars in the Kepler field. Are there flaring specialities associated with the giant nature?

K. Oláh, Zs. Kővári, M. N. Günther +4

We aim to give a reliable estimate of the number of flaring giant stars in the Kepler field. By analyzing the flaring activity of these stars we explore their flare statistics and…

Complex Modulation of Rapidly Rotating Young M Dwarfs: Adding Pieces to the Puzzle

Maximilian N. Günther, David A. Berardo, Elsa Ducrot +37

New sets of young M dwarfs with complex, sharp-peaked, and strictly periodic photometric modulations have recently been discovered with Kepler/K2 (scallop shells) and TESS (complex…

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…

Superflares on the late-type giant KIC 2852961 -- Scaling effect behind flaring at different energy levels

Zs. Kővári, K. Oláh, M. N. Günther +7

The most powerful superflares reaching 10erg bolometric energy are from giant stars. The mechanism behind flaring is supposed to be the magnetic reconnection, which is close…

Physical parameters of selected Gaia mass asteroids

E. Podlewska-Gaca, A. Marciniak, V. Alí-Lagoa +36

Thanks to the Gaia mission, it will be possible to determine the masses of approximately hundreds of large main belt asteroids with very good precision. We currently have diameter…
