Single-dish monitoring of circumstellar water masers
J. Brand, L. Baldacci, D. Engels
We present an overview of the long-term water maser monitoring program of a sample of late-type stars, carried out with the Medicina 32-m and Effelsberg 100-m telescopes, and descr…
A Steeper Stellar Mass Spectrum in the Outer Galaxy?
J. Brand, J. G. A. Wouterloot, A. L. Rudolph +1
We discuss the results of high-resolution (~0.1-0.2 pc) BIMA CO observations of the central regions of 3 molecular clouds in the far-outer Galaxy (FOG). We identify clumps and inve…
A study of the H2O maser emission from R Cas
J. Brand, L. Baldacci, D. Engels
We describe the monitoring program we have been carrying out during the past 10 years on a sample of late-type stars, with the Medicina 32-m and Effelsberg 100-m antennas. We discu…
A search for precursors of Ultracompact HII Regions in a sample of luminous IRAS sources. III: Circumstellar Dust Properties
Sergio Molinari, Jan Brand, Riccardo Cesaroni +1
The James Clerk Maxwell Telescope has been used to obtain submillimeter and millimeter continuum photometry of a sample of 30 IRAS sources previously studied in molecular lines and…
