The SPHERE view of three interacting twin disc systems in polarised light
Philipp Weber, Sebastián Pérez, Greta Guidi +12
Dense stellar environments as hosts of ongoing star formation increase the probability of gravitational encounters among stellar systems during the early stages of evolution. Stell…
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…
Astrometric planet search around southern ultracool dwarfs IV. Relative motion of the FORS2/VLT CCD chips
P. F. Lazorenko, J. Sahlmann
We present an investigation of the stability of the two chips in the FORS2 camera CCD mosaic on the basis of astrometric observations of stars in 20 sky fields, some of which were…
The inner dust shell of Betelgeuse detected by polarimetric aperture-masking interferometry
X. Haubois, B. Norris, P. G. Tuthill +9
Theory surrounding the origin of the dust-laden winds from evolved stars remains mired in controversy. Characterizing the formation loci and the dust distribution within approximat…
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…
Two accreting protoplanets around the young star PDS 70
S. Y. Haffert, A. J. Bohn, J. de Boer +5
Newly forming proto-planets are expected to create cavities and substructures in young, gas-rich proto-planetary disks, but they are difficult to detect as they could be confused w…
