Hideyuki Saio Simon Jeffery are exploring models for the evolution of stars formed by the merger of two white dwarfs. The attached movie provides a simulation of the major events involved in the merger process. ... An initial binary system consists of two white dwarfs of masses M 1 and M 2 (given) with an orbital period ( P ). ... We adopt a simple expression for the white dwarf radius as a function of mass (in solar units): . ... The merged star evolution is simulated by a quadratic expansion . ...

... Cosmic Vacuum . Recent observational studies of remote supernovae have suggested the existence of cosmic vacuum with the density which is larger than the total density of all the other forms of cosmic energy in the Universe. Vacuum produces the field of anti-gravity and induces acceleration of the cosmological expansion. ... The discovery of the cosmic vacuum leads to a drastic change in the current concepts concerning the present state of the Universe. ...

Next: Calling Parameters Up: CAL_rawXY2mm Previous: CAL_rawXY2mm Contents . CCF LinCoord holds the positions of distinct reference points of the CCD's (at reference temperature) and the directions in which the counting of rawX and rawY increases. The size of each pixel is stored in CCF MiscData , and also a thermal expansion coefficient. Using these inputs, together with ( rawX,rawY ), the location of each pixel can be given in focal plane coordinates as a function of temperature. ...

As the Universe expands, gravity pulls on the Universe, and slows the expansion down over time. As we look to great distances, we are looking back in time. If we can measure how fast the Universe is expanding in the past, and compare it to how fast it is expanding now, we can see the total gravitational effect of all matter in the Universe. Here we plot the distance between two galaxies as a function of time. ... Universes with lots of material . ...

... 2001: . The distances to 50 galaxies in the vicinity of three most nearby galaxy clusters were measured. The radius of the "zero velocity sphere", isolating each group from the cosmological expansion is in the range from 0.95 to 1.25 Mpc for these groups, leads to the estimates of the total mass of groups ranging from 1.2 to 2.7 trillion solar masses. These results agree with the value of the mean matter density in the Local Universe from 0.05 to 0.10 in critical density units. ...

The proper expansion expresses both and simultaneously in terms of a particular order of generalized spherical harmonics. ... Generalized spherical harmonics start at , and for each , . ... Generalized spherical harmonics obey a sum rule analogous to a familiar one for ordinary spherical harmonics, but it includes an explicit phase factor which depends on the orientation of the two lines of sight. ...
