Next: Star Formation Rate and Up: No Title Previous: Calculation of Evolutionary Tracks . To start calculations, we choose the distributions of the initial binary parameters: the mass of the primary ZAMS component, , binary mass ratio, , orbital separation a . ... whereas the mass ratio distribution is not. ... The zero assumption often made is that the mass ratio distribution has a flat shape, that is binaries with a high mass ratio occur as frequently as those with equal masses. ...

We present a Bayesian approach to calculating the coefficients that convert the outputs of ALMA 183 GHz water-vapour radiometers into estimates of path fluctuations that can be used to correct the observed interferometric visibilities. ... Please note that the files"COPYING" in each of the distribution packages have GPL listed but it is in fact LGPL which applies. ... This is the raw data from the SMA used in the analysis shown in Section 4 of the memo. ...

... The distributions of orbits eccenttricities and of angular momenta for the halo stars and the old disk population are considered. The distributions have gaps separating the halo from the disk and dividing the halo population into three groups. ... Рассмотрены распределения звезд гало и старого населения диска по величине эксцентриситета орбит и угового момента. Распределения имеют провалы, отделяющие гало от диска и делящие населения гало на три группы. ...

... Up: Software Systems and Tools . ... The Starlink Software is a collection of astronomical packages and utilities comprising over 120 separate components. When built, the system needs between 500 and 650 MB disk space (without source) making it ideal for distribution on CD-ROM. Each component has been individually packaged into an easy-to-install bundle for users to obtain over the Internet via a ``point and click'' WWW interface from the Starlink Software Store. ...

... Scheming arXiv:astro-ph abstracts almost an year never offered me an occasion that the fit of the Poisson distribution is tested in different ways, instead it is taken for granted by plugging data and (source) model into a (modified) ? ... Abstract: goodness-of-fit tests based on the Cramer-von Mises statistics are given for the Poisson distribution. ... 2 statistic for testing the goodness of fit in astronomy and this D statistics is considered as a two sided test approximately distributed as a ? ...

... The galaxy NGC 253 is a well-known nearby spiral galaxy showing numerous peculiar features (e.g. a nuclear ring, gas outflow, a bar, and a warp) which we study using tracers of the different gas phases. ... Whereas the X-rays trace the hottest gas component, the Halpha emission, e.g., shows the distribution of the ionized gas at several thousand Kelvin. ...

Since the first stars and then galaxies formed the Universe has been an immense factory converting neutral gas into stellar material. ... In this seminar I will discuss recent results from the Galaxy And Mass Assembly (GAMA) survey, probing the assembly of stellar mass though both in-situ star formation (as traced by multiple SFR indicators) and interactions (both mergers and interaction induced star-formation) - in galaxies spanning ~4 decades in stellar mass. ...

. I joined NAIC staff in December 1992 via NFRA (Netherlands) and IISc/JAP (India). The topics of my current research include: . (1) Search for Neutral hydrogen in the host galaxies of AGNs at different redshifts. (2) Physical nature and spatial distribution of the ionized component of the interstellar matter. (3) Physics of compact extragalactic radio sources. I am a member of the VLBI group and the Friend of VLBI observations at the observatory. 2008 EVN sessions are here. Tapasi Ghosh .

Figure 1 shows a detailed view of the IRAS4A outflow through the comparison between the H 2 O emission and the emission from several other molecular tracers of gas with different excitation conditions: H 2 , CO(3-2), CO(14-13), and CO(6-5). The figure nicely reveals where shocks deposit energy into the molecular cloud, lighting up the water emission along the outflow . ...

... 88, Jan. 1983, p. 1-15. l. A survey of extragalactic radio sources made using driven declination scans is reported covering an area of about 0.07 sr to a limiting flux density of 35 mJy. The fast-scan survey was carried out at a galactic latitude greater than 17 deg with the NRAO 91-m telescope operating at 4.755 GHz, and the 480 sources detected were reobserved at 1.4 GHz with the National Astronomy and Ionosphere Center 305-m telescope at Arecibo. ...
