The Appearance of Non-Spherical Systems. Application to LMXB
Różańska, A.; Madej, J.; Bełdycki, B. +2 more
We study the appearance of the neutron star-accretion disk system as seen by a distant observer in the UV/X-ray domain. The observed intensity spectra are computed assuming non-spherical geometry of the whole system, in which outgoing spectrum is not represented by the flux spectrum, the latter being valid for spherically symmetric objects. Intens…
On the Distance Measurements toward Young Milky Way Objects. I. Study of IC 2944
Krełowski, J.; Strobel, A.; Bondar, A. +1 more
We compare distances to a very young stellar aggregate, IC 2944, using three methods: direct parallaxes of Gaia, spectrophotometric parallax and our method based on intensities of interstellar CaII lines. The discrepancies between spectrophotometric distances and those, based on CaII K and H lines, were already reported. The interstellar CaII H an…
