Technologies and science archives for ultraviolet astronomy

Astrophysics and Space Science, 2014
This paper summarizes 17 talks presented during the Technological sessions at the “Challenges in UV Astronomy” conference. It is based on summaries submitted by the presenters, on the slides of their talks, on notes written by the authors, and on additional material kindly submitted to the lead author.

A Discussion on astronomy in the ultraviolet - A study of variable stars in the ultraviolet

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1975
Abstract Some of the OAO-2 ultraviolet observations of intrinsically variable stars are discussed. New data is presented for the Ap variable t Cassiopeiae. The cepheid variables are illustrated by a Ursae Minoris. The explosive variables Nova Serpentis 1970, Nova Aquilae 1918, SS Cygni, and the 1972 supernova in NGC 5253 are compared.

A Discussion on astronomy in the ultraviolet - The ultraviolet spectrum of ζ Tauri

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1975
Abstract This report describes a study of the ultraviolet spectrum of the B-shell star, Tauri. The observational material consists of high-dispersion spectrograms obtained from a rocket experiment launched in November 1972. The spectra cover the wavelength interval, 1100-2050 A, with a resolution of about 0.1 A. The u.v. stellar lines

Ultraviolet Astronomy: Observational Aspects

1967
The several disciplines which are incorporated under the heading ‘space research’ can be placed into the two broad categories of geophysics and astronomy. No hard and fast demarcation can be drawn and a considerable region of overlap exists, including, for example, the moon and planets.

Microchannel plate detectors for ultraviolet astronomy

Space Telescopes and Instrumentation 2024: Ultraviolet to Gamma Ray
Beyond the lifetime of the Hubble Space Telescope, observational access to the ultraviolet (UV) might be quite limited. Therefore, small missions with short development times are required to bridge the gap to future larger missions in this important wavelength range.

Ultraviolet and X-Ray Astronomy

2016
This chapter discusses the astrophysics with photons having an energy up to hundreds of keV. X-rays are not able to penetrate atmosphere and space based observatories are needed. Telescopes for UV and softX-rays use reflective elements based on grazing incidence.

Ultraviolet radiation physics in astronomy and geophysics

Journal of Quantitative Spectroscopy and Radiative Transfer, 1962
Abstract The astrophysicist has been compelled, in his studies of the solar and stellar atmospheres, to abandon in some cases the simpler “local thermodynamic equilibrium” approach. The new approach assumes statistical equilibrium and writes equations which concern the transfer of energy.
