Semi-analytic Continuum Spectra of Type II Supernovae and the Expanding Photosphere Method of Distance Determination
We extend the approximate radiative transfer analysis of Hershkowitz, Linder, and Wagoner (1986) to a more general class of supernova model atmospheres, using a simple fit to the effective continuum opacity produced by lines (Wagoner, Perez, and Vasu 1991). At the low densities considered, the populations of the excited states of hydrogen are governed mainly by photoionization and recombination...
متن کاملDistance determinations using type II supernovae and the expanding photosphere method
Due to their high intrinsic brightness, caused by the disruption of the progenitor envelope by the shock-wave initiated at the bounce of the collapsing core, hydrogen-rich (type II) supernovae (SN) can be used as lighthouses to constrain distances in the Universe using variants of the Baade-Wesselink method. Based on a large set of CMFGEN models (Hillier & Miller 1998) covering the photospheric...
متن کاملExpanding Access to Distance Learning using Learning Objects
This work describes BROAD, a set of learning object metadata, focusing on learning criteria that refines and extends current educational metadata and suggests a check list with information about learning objects usage scenario. It firstly argues learning objects and a metadata standard, presenting the most widely used metadata models, and then presents BROAD, our metadata basic schema, which in...
متن کاملSn 1993j Vlbi (iv): a Geometric Determination of the Distance to M81 with the Expanding Shock Front Method
We compare the angular expansion velocities, determined with VLBI, with the linear expansion velocities measured from optical spectra for supernova 1993J in the galaxy M81, over the period from 7 d to ∼9 yr after shock breakout. The high degree of isotropy of the radio shell’s expansion, within 5.5%, with the projection of the radio shell being circular within even 1.4%, and the consistency of ...
متن کاملDistance Determination Using X - Ray Scattering
We examine the feasibility of using dust-scattered X-rays for direct determination of distances to nearby galaxies with bright background AGNs, QSOs, or GRBs. We show how the Chandra X-Ray Observatory could be used to determine the distance to M31 to an unprecedented absolute accuracy of ∼ 1%.
