1. Vladimir Marsakov Publication List
Scale-heights of the Galactic disk subsytems with different ages and metallicities . V.Marsakov & Yu. ... It is based on the fact, that all stars cross the disk plane several times during their Galactic orbital period. ... We have used our representative sample of nearby disk F2-G2 stars Marsakov & Shevelev (1995) in which fundamental stellar parameters was determined on the basis of published date on uvby-photometry, proper motion and radial velocities. ... Marsakov V.A., Shevelev Yu.G. Bull. ...

2. Frequency distribution of galactic binaries
Next: Structure of the Galaxy Up: Model of the Galaxy Previous: Model of the Galaxy . As discussed above (Section 6 ), galactic binary systems are assumed to be distributed logarithmically along their semi-major axis A (Abt and Levy, 1976[ 2 ]), . ... Figure 40: Number of binary stars per frequency decade. ... As the observed distribution of binary periods is flat (equation ( 15.3.1 )), the normalization constant is the total number of galactic binaries per frequency decade: . ...

5. Galactic distribution and absolute magnitudes
... The distribution of galactic RCB stars is controversial. Several authors have argued that they belong to a thick galactic disk, and are thus old Population I stars. ... However, their distribution and space velocities suggest they may alternatively belong to the even older galactic bulge (Population II, [ Drilling 1986 ]). ... These are the only RCB stars for which a distance is known and hence for which an absolute magnitude can be deduced. ...

6. *qpspec* - Extraction of Photon Distributions from QPOE files
Next: Spectral Extraction of Point Up: Spectral Analysis Previous: Structure of the Spectral . A pulse height distribution can be extracted from a QPOE file only if the event structure is `large', `region', or `full'. ... With the new RDF format files, the output from qpspec for most instruments is split into three files: . ... source off-axis histogram . ... background off-axis histogram . For Einstein IPC, there are no off-axis histogram files, but there is a BAL histogram file, _bal.tab. ...
