Very Large Array monitoring of 1720 MHz OH masers toward the Galactic Center
Array monitoring Galactic Center
2011/10/13
We present the first variability study of the 1720 MHz OH masers located in the Galactic Center. Most of these masers are associated with the interaction between the supernova remnant SgrAEast and the...
Mid-infrared interferometric monitoring of evolved stars - The dust shell around the Mira variable RR Aql at 13 epochs
Techniques:interferometric – Stars:AGB – Stars:atmospheres – Stars:mass loss – Stars:individual:RR Aql
2011/9/28
We obtained 13 epochs of mid-infrared interferometry with the MIDI instrument at the VLTI between April 2004 and July 2007, covering pulsation phases 0.45-0.85 within four cycles. The data are modeled...

MONITORING ACTIVE STARS 29 DRA,12 CAM AND COLOUR EXCESS OF II PEG
Stars late type-starspots-Stars individual 29 Dra, 12 Cam, II Peg
2009/2/11
We present the BV light curves analysis of late-type, long-period
stars 29 Dra, 12 Cam for the season 2005/2006, and shorter-period star II Peg for
the same season. High latitude spots (alternativel...
