Detection of atmospheric species and dynamics in the bloated hot Jupiter WASP-172~b with ESPRESSO
J. V. Seidel, B. Prinoth, E. Knudstrup +3
The population of strongly irradiated Jupiter-sized planets has no equivalent in the Solar System. It is characterised by strongly bloated atmospheres and atmospheric large-scale h…
On the need of an ultramassive black hole in OJ 287
Mauri J. Valtonen, Staszek Zola, Achamveedu Gopakumar +25
The highly variable blazar OJ~287 is commonly discussed as an example of a binary black hole system. The 130 year long optical light curve is well explained by a model where the ce…
Observational Implications of OJ 287's Predicted 2022 Disk Impact in the Black Hole Binary Model
Mauri J. Valtonen, Lankeswar Dey, Achamveedu Gopakumar +24
We present a summary of the results of the OJ 287 observational campaign, which was carried out during the 2021/2022 observational season. This season is special in the binary mode…
Refining the 2022 OJ 287 impact flare arrival epoch
Mauri J. Valtonen, Staszek Zola, Gopakumar +24
The bright blazar OJ~287 routinely parades high brightness bremsstrahlung flares, which are explained as being a result of a secondary supermassive black hole (SMBH) impacting the…
The low density, hot Jupiter TOI-640 b is on a polar orbit
Emil Knudstrup, Simon H. Albrecht, Davide Gandolfi +17
TOI-640 b is a hot, puffy Jupiter with a mass of M and radius of R, orbiting a slightly evolved F-type star with a separation of…
An Earth-sized Planet around an M5 Dwarf Star at 22 pc
Teruyuki Hirano, Fei Dai, John H. Livingston +46
We report on the discovery of an Earth-sized transiting planet () in a day orbit around K2-415 (EPIC 211414619), an M5V star at 22 pc. The pla…
