Carinae: high angular resolution continuum, H30 and He30 ALMA images
Z. Abraham, P. P. B. Beaklini, P. Cox +2
We present images of Carinae in the recombination lines H30 and He30 and the underlying continuum with 50~mas resolution (110 AU), obtained with ALMA. For the first time,…
APEX mapping of H3O+ in the Sgr B2 region
F. F. S. van der Tak, ; A. Belloche, P. Schilke +5
The cosmic-ray ionization rate (zeta) of dense molecular clouds is a key parameter for their dynamics and chemistry. Variations of zeta are well established, but it is unclear if t…
Millimeter-wave emission during the 2003 low excitation phase of eta Carinae
Z. Abraham, D. Falceta-Goncalves, T. P. Dominici +5
In this paper we present observations of eta Carinae in the 1.3 mm and 7 mm radio continuum, during the 2003.5 low excitation phase. The expected minimum in the light curves was co…
Circumstellar masers in the Magellanic Clouds
Jacco Th. van Loon, Albert A. Zijlstra, Valentin Bujarrabal +1
We have searched for 22 GHz H2O and 43/86/129 GHz SiO masers in bright IRAS point sources in the SMC and LMC, to test whether the kinematics of the mass loss from these stars depen…
Discovery of the first extra-galactic SiO maser
Jacco Th. van Loon, Albert A. Zijlstra, Valentin Bujarrabal +1
We report on the detection of SiO J=2--1 v=1 (86 GHz) maser emission from the red supergiant IRAS04553--6825 in the LMC. It has thereby become the first known source of SiO maser e…
