1. CTI correction
... This loss depends on several parameters, in particular on the position where the photon was detected, its energy, the temperature of the CCD, and the saturation of traps by charges preceding along the readout direction. ... For deriving the CTI, each CCD column was split into macro pixels, which were determined by adaptive binning to contain a sufficient number of first singles around the line feature. ...

... A closed surface (i.e. a compact surface without boundary) is homeomorphic to either a sphere with g handles (a connected sum of a sphere with g tori) or to a sphere with g M obius bands attached (a connected sum of a sphere with g copies of RP 2 ). A compact surface with boundary is homeomorphic to a closed surface with a nite number of disks deleted. ... Prove that on the sphere with g handles the maximal number of nonintersecting closed curves not dividing this surface is equal to g. IV.11. ...

3. Equations of condition
... Assured of a reliable method of solving the normal equations, we now consider the equations of condition. The observed magnitude m of a star at M air masses with true instrumental magnitude is modelled as ([ 10 ], [ 28 ]) . ... The effective extinction coefficient depends on the effective spectral gradient [ 29 ] of the star, for which we use some color index, affected by half the atmospheric reddening ([ 26 ], [ 10 ]): . ... Thus, for the B band of UBV, we use the (U-V) color. ...

4. Enhanced dust heating in the bulges of early-type spiral galaxies
Stellar density and bar strength should affect the temperatures of the cool (T ~ 20-30 K) dust component in the inner regions of galaxies, which implies that the ratio of temperatures in the circumnuclear regions to the disk should depend on Hubble type. ... The strong radiation field in the high stellar density of a galactic bulge tends to heat the cool dust component to higher temperatures, at least in early-type spirals with relatively large bulges, especially when paired with a strong bar. ...

... A molecular cloud in the interstellar medium may be considered as spherical and of uniform density and fixed temperature as it undergoes expansion or contraction. Assume the opacity of material in the molecular cloud has a value . ... How will this affect cloud fragmentation? (e) In the stages of collapse of a gas cloud before it becomes optically thick, its temperature is determined by the balance between compressional heating and radiation of energy from the cloud. ...

Gradients in the Temperature of CMBR M. MELEK Cairo University, Egypt. A nonconventional approach is developed to nd the primordial angular gradient in the temperature of the Cosmic Microwave Background Radiation. It is found that it depends on the nowadays recent detected value of the angular gradient in the temperature of the CMBR, di erent rates of universe's expansion through its di erent phases and the cosmic time period of each phase. ...

16. Thermal Emission From Isolated Pulsars
... To determine a lower limit to the sensitivity of current observations to measurements of NS surface temperatures, we have used data from the Einstein Slew Survey (Elvis et al. 1990) to establish temperature limits for 275 pulsars which received nonzero exposure during the survey. ... Filled squares correspond to pulsars actually detected in the survey data; the smaller symbols correspond to upper limits to the count rates. ... Click here for plot of x-ray data vs. cooling curves. ...

17. Future of the Galaxy
... Line radiative transfer in C 18 O, HCO + , and CS lines is considered in a spherically symmetric chemo-dynamical model of a starless core, evolution of which is driven by the ambipolar diffusion. Theoretical line profiles are compared to observational data on the well-known L1544 core, which is one of possible candidates for collapsing protostellar clouds. ... Comparison between modelled and observed spectra suggests that L1544 has flattened structure and is observed at some inclination. ...
