Lu Bai, Shenghong Gu, Xiaobin Wang +3
High-precision transit observations provide excellent opportunities for characterizing the physical properties of exoplanetary systems. These physical properties supply many pieces…
A highly mutually-inclined, compact warm-Jupiter system KOI-984 ?
Leilei Sun, Panagiotis Ioannidis, Shenghong Gu +6
The discovery of a population of close-orbiting giant planets ( 1 au) has raised a number of questions about their origins and dynamical histories. These issues have still not…
H and He I absorption in HAT-P-32 b observed with CARMENES -- Detection of Roche lobe overflow and mass loss
S. Czesla, M. Lampón, J. Sanz-Forcada +22
We analyze two high-resolution spectral transit time series of the hot Jupiter HAT-P-32 b obtained with the CARMENES spectrograph. Our new XMM-Newton X-ray observations of the syst…
