... Today this year's largest group of sunspots will cross the Sun's central meridian. ... The next day, the number of spots in the group reached five, and the day after, on June 2nd, it was possible to count thirteen sunspots on solar disk, which had been clear prior to this. ... This year's two most powerful active areas, which passed across the solar disk at the beginning of May, 2009, are set to appear in the Sun's eastern sector in two days, on June 6th. ...

. I will review my biography of Jacobus Cornelius Kapteyn that is about to appear. I started some early work on this while visiting Stromlo four years ago, after Ken and I completed an Annual Reviews chapter. I will focus on Kapteyn s organizational and astronomical work. name=Federico Lelli .

... V838 Mon is a member of a new class of eruptive variables which appear as a peculiar novae having late K-M type spectra in their outburst. Before its outburst, it was a wide binary system of B3V type stars. ... The B3V companion was seen in the outburst in the UV spectrum taken with HST (Rauch et al., ... In the latest spectra, the light of B3V companion was predominating in the short-wave photometric bands. ... CCD blue frames of V838 Mon before the eclipse (left) and in the eclipse (right). ...

To run a process in the background as a job and carry on working add an (ampersand) at the end of the command line. ... The shell forks a child process to run the command and displays the job number ( [ n ] ) and the PID (Process IDentifier) number. ... If the command is likely to produce error messages you will need to redirect standard error. ... Do not run an interactive command that requires you to type something at the terminal as a background job. ... You will then have to kill its process . ...

The perturbation method is based on the small-parameter expansion of an unknown solution of the light scattering problem in a vicinity of the exact solution. ... The only probably exclusion is the case of anisotropic particles for which the rigid solution is either impossible or too complicated. For such problems the perturbation method can give information of the first approximation, which is important for understanding of the basic principles of influences of the material anisotropy. ...

In order to measure the density of the Universe, it is necessary to sample a region that is larger than the scale on which the Universe becomes approximately homogeneous. ... When applied to clusters of galaxies we find a mass to luminosity ratio that implies a density of the Universe that is about 0.3 times the critical density. ... Thus the mass-to-muinosity ratio appears to vary with the size of the region measured, from 3 in the solar neighborhood to 30 in galaxies to 300 in clusters of galaxies. ...

... Now an international team of astrophysicists studying the RXTE data has detected what is known as a magnetar ­ the most magnetic object in the universe. ... The basic pulsar model involves a magnetic dipole field tilted with respect to the rotation axis, beaming radio waves along the dipole axis as the star spins. ... However, for such high magnetic fields the proton cyclotron line, normally hidden in the highly absorbed optical/UV region, is expected to show up at energies of a few keV . ...

Seven months ago, on Mar 19, 2008, at 09:12 Moscow time, a new star appeared on the sky. The Sun had already risen over the Russia, but people of the Western hemisphere might be able to see by their eyes a faint starlet near one of Bootes constellation stars. This starlet appeared and faded by an order of magnitude in a minute. Astronomers named it GRB080319B or, informally, the Naked-Eye Burst, as it was twice as bright as human eye can see a star. ...

. The temperature of degenerating is the temperature below which there appear the quantum effects connected with the indenty of the particles. For bose-gas this temperature Td is equal to the one below which the condensation of Bose-Einstein occurs. Td = Ef/ k , where Ef - maximum energy of particles at T = 0 (fermy-energy), k - constant of Boltzman ( k = 1,3807*10^-23 Dg/K). Back .
