Water vapour masers in long-period variable stars III. Mira variables U Her and RR Aql
A. Winnberg, J. Brand, D. Engels
Within the 'Medicina/Effelsberg H2O maser monitoring program' we observed U Her and RR Aql at 22-GHz for about two decades between 1990 and 2011, with a gap between 1997 and 2000 i…
Patterns in water maser emission of evolved stars on the timescale of decades
Jan Brand, Dieter Engels, Anders Winnberg
We present our past and current long-term monitoring program of water masers in the circumstellar envelopes of evolved stars, augmented by occasional interferometric observations.…
Water vapour masers in long-period variable stars II. The semi-regular variables R Crt and RT Vir
J. Brand, D. Engels, A. Winnberg
Within the 'Medicina/Effelsberg H2O maser monitoring program' we have observed the maser emission of R Crt and RT Vir for more than two decades. To get insight in the distribution…
Galactocentric variation of the gas-to-dust ratio and its relation with metallicity
A. Giannetti, S. Leurini, C. Koenig +6
(Abridged) Context: The assumption of a gas-to-dust mass ratio (γ) is a common approach to estimate the basic properties of molecular clouds, such as total mass and column density…
Recurring OH Flares towards o Ceti: I. location and structure of the 1990s' and 2010s' events
S. Etoka, E. Gerard, A. M. S. Richards +3
We present the analysis of the onset of the new 2010s' OH flaring event detected in the OH ground-state main line at 1665~MHz towards o Ceti and compare its characteristics with th…
Italian Science Case for ALMA Band 2+3
M. T. Beltran, E. Bianchi, J. Brand +18
The Premiale Project "Science and Technology in Italy for the upgraded ALMA Observatory - iALMA" has the goal of strengthening the scientific, technological and industrial Italian…
