Radial Velocity Survey for Planets around Young stars (RVSPY) A transiting warm super-Jovian planet around HD 114082, a young star with a debris disk
O. Zakhozhay, R. Launhardt, T. Trifonov +7
Aiming to detect planetary companions to young stars with debris disks via the radial velocity method, we observed HD114082 during April 2018 - August 2022 as one of the targets of…
Convective Line Shifts in the Spectra of Solar-Type Stars
V. A. Sheminova
The Doppler line shifts in the spectra of the Sun and stars with effective temperatures from 4800 to 6200 K were measured and the average connective (granulation) velocities were e…
Generalised Ellis-Bronnikov Wormholes in Gravity
Oleksii Sokoliuk, Sanjay Mandal, P. K. Sahoo +1
In this manuscript, we construct generalized Ellis-Bronnikov wormholes in the context of modified theories of gravity. We consider that the matter driving the wormhole satis…
Kuchowicz gravastars in the braneworld formalism
Oleksii Sokoliuk, Alexander Baransky, P. K. Sahoo
In the current letter, we study isotropic static spherically symmetric gravastars without charge under the framework of braneworld gravity (dimensionally reduced RS-II braneworld w…
New exocomets of Pic
Ya. Pavlenko, I. Kulyk, O. Shubina +3
Aims. The aim of our work is to analyze the light curves of Pic recently observed by TESS in sectors 32, 33, and 34, searching for the signatures of exocomet transits. Methods.…
Dynamical architecture of the HD 107148 system
Jan Eberhardt, Trifon Trifonov, Martin Kürster +15
We present an independent Doppler validation and dynamical orbital analysis of the two-planet system HD 107148, which was recently announced in Rosenthal et al. (2021). Our detaile…
