VLBA Survey of OH Masers in Star-Forming Regions II: Satellite Lines
A. E. Ruiz-Velasco, D. Felli, V. Migenes +1
Using the Very Long Baseline Array (VLBA) we performed a high resolution OH maser survey in Galactic star-forming regions (SFRs). We observed all the ground state spectral lines: t…
Near-infrared spectro-interferometry of three OH/IR Stars with the VLTI/AMBER instrument
A. E. Ruiz-Velasco, M. Wittkowski, A. Wachter +2
We investigate the molecular and dusty environment of OH/IR stars in order to characterize the mass-loss process during the tip-AGB superwind phase. Employing the AMBER instrument…
Structure and shaping processes within the extended atmospheres of AGB stars
M. Wittkowski, D. A. Boboltz, I. Karovicova +4
We present recent studies using the near-infrared instrument AMBER of the VLT Interferometer (VLTI) to investigate the structure and shaping processes within the extended atmospher…
The extended atmospheres of Mira variables probed by VLTI, VLBA, and APEX
M. Wittkowski, D. A. Boboltz, C. de Breuck +9
We present an overview on our project to study the extended atmospheres and dust formation zones of Mira stars using coordinated observations with the Very Large Telescope Interfer…
High resolution OH maser survey in star forming regions
A. E. Ruiz-Velasco, V. Migenes, V. Slysh +1
We present results of a high resolution survey of OH masers in Galactic Star Forming Regions in order to study the maser emission and establish a list of suitable candidates for hi…
