Search for planets in hot Jupiter systems with multi-sector TESS photometry. III. A study of ten systems enhanced with new ground-based photometry
G. Maciejewski, M. Fernández, A. Sota +12
The loneliness of hot Jupiters supports the high-eccentricity migration as a primary path leading to the formation of systems with those planets stripped of any close-in planetary…
Planet-star interactions with precise transit timing. III. Entering the regime of dynamical tides
G. Maciejewski, M. Fernandez, A. Sota +14
Hot Jupiters on extremely short-period orbits are expected to be unstable to tidal dissipation and spiral toward their host stars. That is because they transfer the angular momentu…
YETI follow-up observations of the T Tauri star CVSO30 with transit-like dips
R. Bischoff, St. Raetz, M. Fernández +13
The T Tauri star CVSO30, also known as PTFO8-8695, was studied intensively with ground based telescopes as well as with satellites over the last decade. It showed a variable light…
The origin of the high-mass X-ray binary 4U 2206+54/BD +53 2790
V. Hambaryan, K. A. Stoyanov, M. Mugrauer +7
Based on the Gaia EDR3 astrometric parameters and our new systemic radial velocity of the high-mass X-ray binary 4U 2206+54/BD+53 2790, we studied the trace back motion of the syst…
Identification of additional young nearby runaway stars based on Gaia data release 2 observations and the lithium test
R. Bischoff, M. Mugrauer, G. Torres +4
Runaway stars are characterised by their remarkably high space velocities, and the study of their formation mechanisms has attracted considerable interest. Young, nearby runaway st…
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…
Follow-up imaging observations of comet 2I/Borisov
M. Mugrauer, R. Bischoff, W. Stenglein +3
Follow-up imaging observations of the first detected interstellar comet 2I/Borisov are presented, which were carried out with the Schmidt-Teleskop-Kamera at the University Observat…
