Massive runaway star HD 254577: the pre-supernova binary companion to the progenitor of the supernova remnant IC 443
B. Dinçel, G. Paylı, S. K. Yerli +9
The secondaries of the massive binary systems can be found as runaway stars after being ejected due to the supernova (SN) of the more massive component. We search for such stars in…
Radial Velocity Monitoring and Analysis of Gaia Astrometry of Selected Intermediate Mass Stars to Constrain Their Multiplicity Status
J. Bätz, M. Mugrauer, K. -U. Michel +5
We present new radial velocity measurements of 13 selected intermediate mass stars (2 - 6 M). The measurements were performed between 29 April and 6 September 2024 at the U…
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…
Gaia Search for stellar Companions of TESS Objects of Interest IV
M. Mugrauer, J. Rück, K. -U. Michel
We present the latest results of our ongoing multiplicity study of (Community) TESS Objects of Interest, using astrometric and photometric data from the ESA-Gaia mission to detect…
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…
Search for (sub)stellar companions of exoplanet hosts by exploring the second ESA-Gaia data release
K. -U. Michel, M. Mugrauer
We present the latest results of an ongoing multiplicity survey of exoplanet hosts, which was initiated at the Astrophysical Institute and University Observatory Jena, using data f…
Planet-star interactions with precise transit timing. I. The refined orbital decay rate for WASP-12 b and initial constraints for HAT-P-23 b, KELT-1 b, KELT-16 b, WASP-33 b, and WASP-103 b
G. Maciejewski, M. Fernández, F. Aceituno +11
Theoretical calculations and some indirect observations show that massive exoplanets on tight orbits must decay due to tidal dissipation within their host stars. This orbital evolu…
