Mid-infrared characterization of the planetary-mass companion ROXs 42B b
Sebastian Daemgen, Kamen Todorov, Jasmin Silva +10
We present new Keck/NIRC2 35 m infrared photometry of the planetary-mass companion to ROXS 42B in , and for the first time in Brackett- (Br) and in $M_\mathrm…
Direct Imaging and Spectroscopy of a Candidate Companion Below/Near the Deuterium-Burning Limit In The Young Binary Star System, ROXs 42B
Thayne Currie, Sebastian Daemgen, John Debes +5
We present near-infrared high-contrast imaging photometry and integral field spectroscopy of ROXs 42B, a binary M0 member of the 1--3 Myr-old Ophiuchus star-forming region, fro…
Orbits and masses in the young triple system TWA 5
R. Köhler, T. Ratzka, M. G. Petr-Gotzens +1
We aim to improve the orbital elements and determine the individual masses of the components in the triple system TWA 5. Five new relative astrometric positions in the H band were…
Stellar and circumstellar properties of visual binaries in the Orion Nebula Cluster
S. Correia, G. Duchene, B. Reipurth +8
Our general understanding of multiple star and planet formation is primarily based on observations of young multiple systems in low density regions like Tau-Aur and Oph. Since many…
Protoplanetary disk evolution and stellar parameters of T Tauri binaries in Chamaeleon I
Sebastian Daemgen, Monika G. Petr-Gotzens, Serge Correia +4
This study aims to determine the impact of stellar binary companions on the lifetime and evolution of circumstellar disks in the Chamaeleon I (Cha I) star-forming region by measuri…
Multiplicity of rapidly oscillating Ap stars
M. Schoeller, S. Correia, S. Hubrig +1
Rapidly oscillating Ap (roAp) stars have rarely been found in binary or higher order multiple systems. This might have implications for their origin. We intend to study the multipl…
