Black Hole masses for 14 gravitational lensed quasars
A. Melo, V. Motta, J. Mejía-Restrepo +7
We estimate black hole masses (M) for 14 gravitationally lensed quasars using the Balmer lines along with estimates based on MgII and CIV emission lines for four and two…
Apocenter pile-up and arcs: a narrow dust ring around HD 129590
Johan Olofsson, Philippe Thébault, Amelia Bayo +6
Observations of debris disks have significantly improved over the past decades, both in terms of sensitivity and spatial resolution. At near-infrared wavelengths, new observing str…
The vertical structure of debris disks and the impact of gas
Johan Olofsson, Philippe Thébault, Quentin Kral +10
The vertical structure of debris disks provides clues about their dynamical evolution and the collision rate of the unseen planetesimals. Thanks to the ever-increasing angular reso…
ISPY -- NaCo Imaging Survey for Planets around Young stars. CenteR: the impact of centering and frame selection
N. Godoy, J. Olofsson, A. Bayo +18
Abridged: Direct imaging has made significant progress over the past decade leading to the detection of several giant planets. Observing strategies and data rates vary from instrum…
First black hole mass estimation for the quadruple lensed system WGD2038-4008
A. Melo, V. Motta, N. Godoy +6
The quadruple lensed system WGD2038-4008 was recently discovered with the help of new techniques and observations. Even though black hole mass has been estimated for lensed quasars…
Most EL CVn systems are inner binaries of hierarchical triples
F. Lagos, M. R. Schreiber, S. G. Parsons +2
In spite of their importance for modern astronomy, we do not fully understand how close binary stars containing at least one white dwarf form from main sequence binary stars. The d…
VALES VII: Molecular and ionized gas properties in pressure balanced interstellar medium of starburst galaxies at z ~ 0.15
Juan Molina, Edo Ibar, Nicolas Godoy +9
Context. Spatially resolved observations of the ionized and molecular gas are critical for understanding the physical processes that govern the interstellar medium (ISM) in galaxie…
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…
A dusty benchmark brown dwarf near the ice line of HD 72946
A. -L. Maire, J. -L. Baudino, S. Desidera +12
Context. HD72946 is a bright and nearby solar-type star hosting a low-mass companion at long period (P~16 yr) detected with the radial velocities (RV) method. The companion has a m…
An unusually large gaseous transit in a debris disc
Daniela P. Iglesias, Johan Olofsson, Amelia Bayo +9
We present the detection of an unusually large transient gas absorption in several ionized species in the debris disc star HD 37306 using high-resolution optical spectra. We have b…
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…
ISPY - the NaCo Imaging Survey for Planets around Young stars: A young companion candidate embedded in the R CrA cloud
G. Cugno, S. P. Quanz, R. Launhardt +13
Within the NaCo-ISPY exoplanet imaging program, we aim at detecting and characterizing the population of low-mass companions at wide separations (10AU), focusing in partic…
Spectral and orbital characterisation of the directly imaged giant planet HIP 65426 b
A. C. Cheetham, M. Samland, S. S. Brems +38
HIP 65426 b is a recently discovered exoplanet imaged during the course of the SPHERE-SHINE survey. Here we present new and observations of the planet from the NACO instr…
Resolving faint structures in the debris disk around TWA7
J. Olofsson, R. G. van Holstein, A. Boccaletti +51
Debris disks are the intrinsic by-products of the star and planet formation processes. Most likely due to instrumental limitations and their natural faintness, little is known abou…
The bimodal initial mass function in the Orion Nebula Cloud
H. Drass, M. Haas, R. Chini +5
Due to its youth, proximity and richness the Orion Nebula Cloud (ONC) is an ideal testbed to obtain a comprehensive view on the Initial Mass Function (IMF) down to the planetary ma…
