• Описание конференции:

  The conference, organized by the Isaac Newton Group of Telescopes with financial support from the Instituto de Astrofisica de Canarias, was held in the Hotel H10 Taburiente Playa in Los Cancajos, a quiet beach resort located near the capital Santa Cruz. V838 Mon has displayed a complex light curve characterized by multiple maxima of very different colors, a very red spectral energy distribution, a long phase during which the optical brightness was below the quiescence value while the star remained very bright in the near-IR, and a recent re-warming accompanied by a recovery of the optical luminosity. The spectral evolution of V838 Mon was as peculiar as its light curve. In spite of large ejection velocities at the outburst onset (~500 km/sec), the expanding ejecta never reached optically thin conditions. It remained optically thick and got cooler and cooler with time, initially mimicking a K giant, then making a complete excursion along the whole sequence of M giant spectra down to M10, and finally entering the new realm of L-type supergiants, a spectral type never seen before anywhere in the Universe and characterized by temperatures so low that were previously measured only in brown dwarfs. Besides this, V838 Mon became one of the major attractions in stellar astrophysics over the last few years by displaying a 2 arcmin wide bright circumstellar light-echo, the first one seen in our Galaxy in the last 70 years.
