The AstraLux Multiplicity Survey: Extension to Late M-dwarfs
Markus Janson, Carolina Bergfors, Wolfgang Brandner +4
The distribution of multiplicity among low-mass stars is a key issue to understanding the formation of stars and brown dwarfs, and recent surveys have yielded large enough samples…
Stellar companions to exoplanet host stars: Lucky Imaging of transiting planet hosts
Carolina Bergfors, Wolfgang Brandner, Sebastian Daemgen +7
Observed properties of stars and planets in binary/multiple star systems provide clues to planet formation and evolution. We extended our survey for visual stellar companions to th…
Age spread in Galactic star forming region W3 Main
A. Bik, Th. Henning, A. Stolte +10
We present near-infrared JHKs imaging as well as K-band multi-object spectroscopy of the massive stellar content of W3 Main using LUCI at the LBT. We confirm 13 OB stars by their a…
The AstraLux Large M-dwarf Multiplicity Survey
Markus Janson, Felix Hormuth, Carolina Bergfors +7
We present the results of an extensive high-resolution imaging survey of M-dwarf multiplicity using the Lucky Imaging technique. The survey made use of the AstraLux Norte camera at…
Instantaneous starburst of the massive clusters Westerlund 1 and NGC 3603 YC
Natalia Kudryavtseva, Wolfgang Brandner, Mario Gennaro +9
We present a new method to determine the age spread of resolved stellar populations in a starburst cluster. The method relies on a two-step process. In the first step, kinematic me…
Multiple episodes of star formation in the CN15/16/17 molecular complex
M. Gennaro, A. Bik, W. Brandner +9
We have started a campaign to identify massive star clusters inside bright molecular bubbles towards the Galactic Center. The CN15/16/17 molecular complex is the first example of o…
