SINGULAR POINTS IN THE SOLAR CHROMOSPHERE . ... In the structure of the solar chromosphere, containing information on the configuration of the magnetic field, we have found and identified all the main types of the singular points ( see Fig. 1 ), which are known as inherent features of the 2-D vector field. ... The main types of the singular points are the node, the focus, the center, and the saddle. ... Singular point of the focus type in the solar chromosphere. ...

This newsletter has been formed following the success of similar publications such as the Star Formation Newsletter and AGB Newsletter. ... Also thanks to Bo Reipurth for his LaTex macros. ... Following the first edition of the newsletter will follow the LaTeX template for abstract submissions. It is VERY simple and requires no knowledge of LaTeX to fill out. ...

SWIRL DISTRIBUTION ON THE LUNAR SURFACE: LOCATIONS ANTIPODAL TO THE YOUNG BASINS? ... There are two main classes of hypothesises of the swirl origin: formation of the swirls in the regions antipodal to large impact basins (1), and formation of the swirls in result of cometary impacts (2). ... The Orientale basin is youngest. ... Fig. ... On the other hand, there are two cases of absence of correlation between swirl areas and regions antipodal to impact basins (for small swirl formations). ...

... arXiv.org . astro-ph . ... We fit the near-infrared to radio spectral energy distributions of 30 luminous and ultra-luminous infrared galaxies with pure starburst models or models that include both starburst and AGN components to determine important physical parameters for this population of objects. In particular we constrain the optical depth towards the luminosity source, the star formation rate, the star formation efficiency and the AGN fraction. ...

... AstroCC is a coordinate conversion utility for astronomy. It accepts an object designation or the coordinates of an object and calculates coordinates in alternative systems, and at different dates, times, and locations. It also provides lunar and bright planet coordinates to aid in planning observations. ... BJD values may also be retrieved from http://astroutils.astronomy.ohio-state.edu/time/utc2bjd.html which is based on Eastman et al. ... Coordinate data are obtained from SIMBAD. ...

The 2dF QSO Redshift Survey (2QZ) . ... Before jumping into all the finer details of teh survey, a brief non-astronomer's guide to redshift surveys is available. ... The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure . ...

... It was found that the Sun lies 9?2 pc above the plane of hte Galactic disk in the direction of North Galactic pole and that F0-F9 stars contribute 0.0035 M /pc 3 to the density of the Galactic disk. ... We used this method to determine the scale height of the subsystem of F stars of the Galactic disk, Z 0 =160?10 pc. ... It is suggested that scale height of the metal-poor stars subsystem is due to the infall of the metall-poor intergalactic gas onto the disk. ...

... Limit of star magnitude. If you want to obtain best results, you should use reference stars not more dimly than limiting star magnitude of your telescope. Limiting star magnitude depends on time of an exposition also.) This value should be set as " maximum of star magnitude " in a dialog box " Extraction from catalogue". To find darkest stars in the frame, make the following: . ... Two star magnitudes (m1, m2 in two photometric systems) will be outputted in the window "Information". ...
