HADES RV Programme with HARPS-N at TNG. VII. Rotation and activity of M-Dwarfs from time-series high-resolution spectroscopy of chromospheric indicators

A. Suárez Mascareño, R. Rebolo, J. I. González Hernández +28

We aim to investigate the presence of signatures of magnetic cycles and rotation on a sample of 71 early M-dwarfs from the HADES RV programme using high-resolution time-series spec…

HADES RV Programme with HARPS-N at TNG VI. GJ 3942 b behind dominant activity signals

M. Perger, I. Ribas, M. Damasso +29

Short- to mid-term magnetic phenomena on the stellar surface of M-type stars cannot only resemble the effects of planets in radial velocity data, but also may hide them. We analyze…

The HIP 79977 debris disk in polarized light

N. Engler, H. M. Schmid, Ch. Thalmann +40

We present observations of the known edge-on debris disk around HIP 79977 (HD 146897, F star in Upper Sco, 123 pc), taken with the ZIMPOL differential polarimeter of the SPHERE ins…

In-depth study of moderately young but extremely red, very dusty substellar companion HD206893B

P. Delorme, T. Schmidt, M. Bonnefoy +47

The substellar companion HD206893b has recently been discovered by direct imaging of its disc-bearing host star with the SPHERE instrument. We investigate the atypical properties o…
