Fitting procedure for estimating interstellar extinction at high galactic latitudes

چکیده
Abstract We determine the interstellar extinction in selected high-latitude areas of sky based on Gaia EDR3 astrometry and photometry spectroscopic data from RAVE survey. approximate results with cosecant law each area thus deriving parameters barometric formula for different lines sight. The distribution over entire is described using spherical harmonics. As a result, we get mathematical description visual sight distances Sun which can be used estimating extinction.

Early type stars at high galactic latitudes
We present the result of differential spectral analyses of a further four apparently normal B-type stars. Abundance anomalies (e.g. He, C, N enrichment), slow rotation and/or high gravities suggest that the programme stars are evolved low-mass B-type stars. In order to trace their evolutionary status several scenarios are discussed. Post-AGB evolution can be ruled out. PG 0229+064 and PG 1400+3...
متن کاملInterstellar polarization at high galactic latitudes from distant stars III. Distribution of the polarization vectors – evidence for distinct zones
We make a map of interstellar polarization direction around the North Galactic Pole and study the distribution of the revealed magnetic field lines. We study in detail Markkanen’s (1979) cloud and other local features apparent in the polarization map, and compare them with the IRAS 100 micron map. The elongated Markkanen’s cloud (at a distance of 100–200 pc) and its magnetic field lines coincid...
متن کاملOn the Formation of Perseus Ob1 at High Galactic Latitudes
The Per OB1 association, which contains the remarkable double cluster h and χ Per, is unusual in not having a giant molecular cloud in its vicinity. We show from Hipparcos data that the luminous members of this association exhibits a bulk motion away from the galactic plane, such that their average velocity increases with height above the galactic plane. We find HAeBe and T Tauri stars towards ...
متن کاملGalactic dust polarized emission at high latitudes and CMB polarization
With recent instrumental advances, it might become possible to measure the polarization of the Cosmic Microwave Background (CMB), e.g. by future space missions like MAP and Planck Surveyor. In this paper, we estimate the dust polarized emission in our galaxy which is the major foreground to cope with for measuring the CMB polarization in the Wien part of CMB spectrum. We model the dust polarize...
متن کاملBepposax/pds Serendipitous Detections at High Galactic Latitudes
At a flux limit of∼10 erg cm s in the 20–100 keV band, the PDS instrument on–board BeppoSAX offers the opportunity to study the extragalactic sky with an unprecedented sensitivity. In this work we report on the results of a search in the BeppoSAX archive for serendipitous high energy sources at high galactic latitudes (|b| ≥ 13◦). We have defined a set of twelve regions in which the PDS/MECS cr...
