Southern massive stars at high angular resolution: observational campaign and companion detection
Hugues Sana,J.-B. Le Bouquin,J.-B. Le Bouquin,Sylvestre Lacour,Jean-Philippe Berger,Gilles Duvert,Gilles Duvert,L. Gauchet,Barnaby Norris,Johan Olofsson,D. Pickel,G. Zins,G. Zins,Olivier Absil,A. de Koter,A. de Koter,Kaitlin M. Kratter,Kaitlin M. Kratter,O. Schnurr,Hans Zinnecker +19 more
TL;DR: The Southern MAssive Stars at High angular resolution survey (smash+) was designed to fill this gap by providing the first systematic interferometric survey of Galactic massive stars as mentioned in this paper.
Journal ArticleDOI

TL;DR: In this paper, adaptive optics observations of LkCa 15 that probe within the disk clearing are reported, with accurate source positions over multiple epochs spanning 2009-2015, infer the presence of multiple companions on Keplerian orbits.
Journal ArticleDOI
On the Role of Disks in the Formation of Stellar Systems: A Numerical Parameter Study of Rapid Accretion
Kaitlin M. Kratter,Christopher D. Matzner,Mark R. Krumholz,Richard I. Klein,Richard I. Klein +4 more
TL;DR: In this paper, the authors study rapidly accreting, gravitationally unstable disks with a series of idealized global, numerical experiments using the code ORION and show that the disk-to-star accretion rate is proportional to the infall rate and governed by gravitational torques generated by lowm spiral modes.
Journal ArticleDOI
Gravitational Instabilities in Circumstellar Disks
TL;DR: A review of the role of gravity in the formation of star and planet formation is presented in this article, with a brief overview of the observational evidence for massive disks that might be subject to gravitational instability and a survey of numerical simulations that aim to capture the nonlinear evolution.
Journal ArticleDOI
The runts of the litter: why planets formed through gravitational instability can only be failed binary stars
TL;DR: In this article, the authors discuss the local requirements for fragmentation and the initial fragment mass scales, and then consider whether the fragment's subsequent growth can be terminated within the planetary mass regime.
