Chapter Czechia closes

Posted December 22, 2016 By grigoris

So…these are my final moments in the office that I spend the last 2.5 (almost) years! A lot of memories and experience gained. I am grateful to Michaela Kraus and other colleagues for their hospitality and their interest in my scientific and social life. Nevertheless, a cycle has finished and now I move on. In […]

The 2016 Massive Stars meeting in New Zealand

Posted December 1, 2016 By grigoris

The Massive Stars meeting of 2016 takes place in Auckland, in New Zealand. I was fortunate enough to be given the opportunity to present two works, one poster and one talk during the splinter session on X-rays from massive stars. I have been working hard to finish them, producing the final results almost a day […]

Our most recent work comes as a proceedings paper for the conference “Stars: from collapse to collapse” (Special Astrophysical Observatory, Nizhnij Arkhyz, Karachai-Cherkessian Republic, Russia, 3-7 October 2016): The yellow hypergiant – B[e] supergiant connection A. Aret, M. Kraus, I. Kolka, G. Maravelias B[e] supergiants and yellow hypergiants share a number of common properties regarding […]

Workshop on Python and IRAF/PyRAF

Posted November 16, 2016 By grigoris

Between 12 to 19 of September 2016, we organized the Ondřejov Summer School 2016, which was held at the Stellar Stellar Department of the Astronomical Institute (Czech Academy of Sciences), in Ondřejov. The main aim of the school was to provide students hands-on experience with real observational data, i.e. to understand observations, reduce them, and […]

How many exoplanets in our Galaxy?

Posted October 30, 2016 By grigoris

In Cassan et al. 2012 (Nature, 481, 167), “One or more bound planets per Milky Way star from microlensing observations“) we read the following very interesting statement: Here we report a statistical analysis of microlensing data (gathered in 2002–07) that reveals the fraction of bound planets 0.5–10 AU (Sun–Earth distance) from their stars. We find […]

LambdaCDM vs. MOND

Posted October 21, 2016 By grigoris

Even though the fight between Lambda(Λ)CDM and MOND theories is a confirmed fact, automatic processes (like listing of new arxiv papers) make it more … provocative and/or funny.

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 the circumstellar disk-like structure of […]

LaTeX tip to comment out large portion of text

Posted October 10, 2016 By grigoris

Not very obvious but: \iffalse blablabla blublublublu and some more bla here \fi so LaTeX doesn’t compile anything within this if clause. [1] TeX.stackexchange- Commenting out large sections, accessed on Oct 10, 2016

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 LMC B[e] supergiant LHA 120-S […]
