Properties of luminous red supergiant stars in the Magellanic Clouds S. de Wit, A.Z. Bonanos, F. Tramper, M. Yang, G. Maravelias, K. Boutsia, N. Britavskiy, and E. Zapartas There is evidence that some red supergiants (RSGs) experience short lived phases of extreme mass loss, producing copious amounts of dust. These …
During the last weekend I went hiking – albeit with a company of many astronomers! – a bit outside Santiago (we actually camp at Banos Colina in Cajon del Maipo). The mountain views were impressive, but during night I got another stunning view. As we were relaxing in the thermal …
Finally after almost a year, our proceedings paper on the B[e] supergiant LHA 120-S 73 is out! It is based on a poster (2015-58aaa-torres-s73) presented on the 58th Annual Meeting of the Argentinian Astronomical Society (La Plata, Argentina, Sep 14-18, 2015) and connected also with our last refereed paper. Exploring …
Inhomogeneous molecular ring around the B[e] supergiant LHA 120-S 73 M. Kraus, L.S. Cidale, M.L. Arias, G. Maravelias, D.H. Nickeler, A.F. Torres, M. Borges Fernandes, A. Aret, M. Cure, R. Vallverdu, R.H. Barba We aim to improve our knowledge on the structure and dynamics of the circumstellar disk of the …
Disk tracing for B[e] supergiants in the Magellanic Clouds G. Maravelias, M. Kraus, A. Aret B[e] supergiants are evolved massive stars with a complex circumstellar environment. A number of important emission features probe the structure and the kinematics of the circumstellar material. In our survey of Magellanic Cloud B[e] supergiants …
