Context. Studies of the magnetic characteristics of massive stars have recently received significant attention because they are progenitors of highly magnetised...
Detection of Fe and evidence for TiO in the dayside emission spectrum of WASP-33b
Context. Theoretical studies predict the presence of thermal inversions in the atmosphere of highly irradiated gas giant planets. Recent observations have...
Detection of Fe and Ti on the dayside of the ultrahot Jupiter MASCARA-1b with CARMENES
Ultrahot Jupiters are a type of gaseous exoplanet that orbit extremely close to their host star, resulting in significantly high equilibrium temperatures. In...
Detection of Fe I and Fe II in the atmosphere of MASCARA-2b using a cross-correlation method
Ultra-hot Jupiters are gas giants planets whose dayside temperature is greater than 2200 K as a consequence of the strong irradiation received from the host...
Detection of frequency spacings in the young O-type binary HD 46149 from CoRoT photometry
Aims: Using the CoRoT space based photometry of the O-type binary HD 46149, stellar atmospheric effects related to rotation can be separated from pulsations...
Detection of He I λ10830 Å absorption on HD 189733 b with CARMENES high-resolution transmission spectroscopy
We present three transit observations of HD 189733 b obtained with the high-resolution spectrograph CARMENES at Calar Alto. A strong absorption signal is...
Detection of iron emission lines and a temperature inversion on the dayside of the ultra-hot Jupiter KELT-20b
Ultra-hot Jupiters (UHJs) are gas giants with very high equilibrium temperatures. In recent years, multiple chemical species, including various atoms and ions...
Detection of Na in the atmosphere of the hot Jupiter HAT-P-55b
The spectral signatures of optical absorbers, when combined with those of infrared molecules, play a critical role in constraining the cloud properties of...
Detection of Na in WASP-21b's lower and upper atmosphere
Optical transmission spectroscopy provides crucial constraints on the reference pressure levels and scattering properties for the atmospheres of hot Jupiters...
