Rotation and variability of young very low mass objects
Alexander Scholz, Ray Jayawardhana, Jochen Eisloeffel +1
Variability studies are an important tool to investigate key properties of stars and brown dwarfs. From photometric monitoring we are able to obtain information about rotation and…
Constraining the properties of spots on Pleiades very low mass stars
Alexander Scholz, Jochen Eisloeffel, Dirk Froebrich
We present results of a multi-filter monitoring campaign for very low mass (VLM) stars in the Pleiades. Simultaneous to our I-band time series (Scholz & Eisloeffel 2004), which del…
VPMS J1342+2840 - an unusual quasar from the variability and proper motion survey
H. Meusinger, D. Froebrich, M. Haas +3
We report the discovery of the highly peculiar, radio-loud quasar VPMS J1342+2840 (z ~ 1.3) from the variability and proper motion survey. We present spectroscopic, imaging and pho…
The near-infrared excitation of the HH211 protostellar outflow
Barry O'Connell, Michael D. Smith, Dirk Froebrich +2
The protostellar outflow HH211 is of considerable interest since it is extremely young and highly collimated. Here, we explore the outflow through imaging and spectroscopy in the n…
A Galactic Plane Relative Extinction Map from 2MASS
D. Froebrich, T. P. Ray, G. C. Murphy +1
We present three 14400 square degree relative extinction maps of the Galactic Plane (|b|<20degrees) obtained from 2MASS using accumulative star counts (Wolf diagrams). This method…
