... Phyllosilicates may form in EKB bodies during aqueous alteration [7]. ... The time m required to heat a large EKB body to the water - ice melting point and to melt the ice in its interiors can be estimated from the equation 0 Q exp(-t )dt = Tm T0 c p dT + L f m w , (1) where T0 = 30 K is the adopted value for the initial temperature of the body , Tm = 273 K is the melting temperature of water ice (a good approximation to at P 25 MPa, characteristic for interiors of a EKB ...

The revision of the MASS/DIMM star catalogue N. Shatsky, V. Kornilov March 16, 2008 Abstract The compilation of the (updated) version of the MASS (MASS/DIMM) device target catalogue is described. ... Then the list was cleaned according to following criteria: I. Remove stars too faint for a MASS device. ... Here the color equation of the Sternb erg device was taken: M AS S mag = V mag + 0.45 (B - V ); stars with M AS S mag > 3.2 were removed. ... This was made based on the GCVS4.2 catalogue data. ...
