Detection of He I Å absorption on HD 189733 b with CARMENES high-resolution transmission spectroscopy
M. Salz, S. Czesla, P. C. Schneider +35
We present three transit observations of HD 189733 b obtained with the high-resolution spectrograph CARMENES at Calar Alto. A strong absorption signal is detected in the near-infra…
X-ray and UV emission of the ultrashort-period, low-mass eclipsing binary system BX Tri
V. Perdelwitz, S. Czesla, J. Robrade +2
Close binary systems provide an excellent tool to determine stellar parameters such as radii and masses with a high degree of precision. Due to the high rotational velocities, most…
The atmosphere of WASP-17b: Optical high-resolution transmission spectroscopy
Sara Khalafinejad, Michael Salz, Patricio E. Cubillos +8
High-resolution transmission spectroscopy is a method for understanding the chemical and physical properties of upper exoplanetary atmospheres. Due to large absorption cross-sectio…
Revisiting the connection between magnetic activity, rotation period, and convective turnover time for main-sequence stars
M. Mittag, J. H. M. M. Schmitt, K. -P. Schröder
The connection between stellar rotation, stellar activity, and convective turnover time is revisited with a focus on the sole contribution of magnetic activity to the Ca II H&K emi…
Multiepoch, multiwavelength study of accretion onto T Tauri: X-ray versus optical and UV accretion tracers
P. C. Schneider, H. M. Günther, J. Robrade +2
Classical T Tauri stars (CTTSs) accrete matter from the inner edge of their surrounding circumstellar disks. The impact of the accretion material on the stellar atmosphere results…
Atmospheric mass loss of extrasolar planets orbiting magnetically active host stars
Lalitha Sairam, J. H. M. M. Schmitt, Spandan Dash
Magnetic stellar activity of exoplanet hosts can lead to the production of large amounts of high-energy emission, which irradiates extrasolar planets, located in the immediate vici…
