Planet populations inferred from debris discs: insights from 178 debris systems in the ISPY, LEECH and LIStEN planet-hunting surveys
Tim D. Pearce, Ralf Launhardt, Robert Ostermann +11
We know little about the outermost exoplanets in planetary systems, because our detection methods are insensitive to moderate-mass planets on wide orbits. However, debris discs can…
ISPY -- NACO Imaging Survey for Planets around Young stars: Survey description and results from the first 2.5 years of observations
R. Launhardt, Th. Henning, A. Quirrenbach +21
The occurrence rate of long-period giant planets around young stars is highly uncertain since it is not only governed by the protoplanetary disc structure and planet formation proc…
Detection of H emission from PZ Tel B using SPHERE/ZIMPOL
Arianna Musso Barcucci, Gabriele Cugno, Ralf Launhardt +7
H is a powerful tracer of accretion and chromospheric activity, which has been detected in the case of young brown dwarfs and even recently in planetary mass companions (e.g. PD…
ISPY -- NaCo Imaging Survey for Planets around Young stars. Discovery of an M dwarf in the gap between HD 193571 and its debris ring
Arianna Musso Barcucci, Ralf Launhardt, Grant M. Kennedy +19
Context. The interaction between low-mass companions and the debris discs they reside in is still not fully understood. A debris disc can evolve due to self-stirring, a process in…
