I first read that R136 contained a supermassive object some time ago in the Sunday edition of the Chilean daily newspaper The 30 Doradus Nebula and R136 EI Mercurio, where it was announced that ... "European astronomers discover the most massive star in the Universe!". The 30 Doradus nebula (thus named because it lies in the Since EI Mercurio is almost always wrang I did not take the Constellation of Doradus) is an outstanding complex of gas, announcement very seriously until the paper by Feitzinger and dust and stars in the Large Magellanic Cloud (LMC), the Co-workers (henceforth the Bochum graup) appeared in nearest galaxy to our own.

It is suspected to be a binary because of its high luminosity and its strong X-ray flux, but no periodicity could be established so far. Here, we present new X-shooter multi-epoch spectroscopy of R144 obtained at the ESO Very Large Telescope (VLT). We detect variability in position and/or shape of all the spectral lines. -

This picture was suggested by Sakib Rasool; for more details see http://www.cielaustral.com/galerie/photo95.htm. 1 Editorial Dear Colleagues, It is my pleasure to present you the 159th issue of the Magellanic Clouds Newsletter. I am sure you must have been mesmerized by the cover picture. It is not just stunning but also inspiring. You’re very welcome to e-mail pictures of the Magellanic Clouds or objects in the Magellanic Clouds, that show them in a different light from what we’ve been used to seeing. The Small Magellanic Cloud rises higher in the sky again (and the Antarctic nights are getting longer) so new obser- vations will start to be possible again. Of course radio observations, particle observations and observations from space have never ceased. At radio frequencies, the SKA pathfinders are becoming fully fledged, so watch this space for more great progress. The next issue is planned to be distributed on the 1st of August.

Here I present a comprehensive one-dimensional photochemistry- thermochemistry model developed from the ground up for terrestrial exoplanet at- mospheres. With modern numerical algorithms, the model has desirable features for exoplanet exploration, notably the capacity to treat both thin and thick atmo- spheres ranging from reducing to oxidizing, and to find steady-state solutions start- ing from any reasonable initial conditions. These features make the model the first photochemistry-thermochemistry model applicable for non-hydrogen-dominated thick atmospheres on terrestrial exoplanets. -

A dozen colliding wind X-ray binaries in the star cluster R 136 in the 30 Doradus region Simon F. Portegies Zwart1,2,3, David Pooley3, Walter, H. G. Lewin3 arXiv:astro-ph/0106109v2 9 Apr 2002 1Astronomical Institute “Anton Pannekoek”, Univeristy of Amsterdam, Kruislaan 403, 1098 SJ Amsterdam, NL 2Section Computational Science, Univeristy of Amsterdam, Kruislaan 403, 1098 SJ Amsterdam, NL 3Massachusetts Institute of Technology, Cambridge, MA 02139, USA Subject headings: stars: early-type — stars: Wolf-Rayet — galaxies:) Magellanic Clouds — X-rays: stars — X-rays: binaries — globular clusters: individual (R136) –2– ABSTRACT We analyzed archival Chandra X-ray observations of the central portion of the 30 Doradus region in the Large Magellanic Cloud. The image contains 20 X-ray point sources with luminosities between 5 × 1032 and 2 × 1035 erg s−1 (0.2 – 3.5 keV). A dozen sources have bright WN Wolf-Rayet or spectral type O stars as optical counterparts. Nine of these are within ∼ 3.4pc of R136, the central star cluster of NGC 2070. We derive an empirical relation between the X-ray luminosity and the parameters for the stellar wind of the optical counterpart. The relation gives good agreement for known colliding wind binaries in the Milky Way Galaxy and for the identified X-ray sources in NGC 2070. We conclude that probably all identified X-ray sources in NGC 2070 are colliding wind binaries and that they are not associated with compact objects. This conclusion contradicts Wang (1995) who argued, using ROSAT data, that two earlier discovered X-ray sources are accreting black-hole binaries. -
