The Brave New World of Binary Star Studies

Guinan, Edward F.; Engle, Scott G.

In this paper we discuss some of the new and exciting developments in the study of binary stars. Recent technological advances (such as CCDs) now make it possible (even easy) to study faint, astrophysically important binaries that in the past could only be done with large 4 + meter class telescopes. Also, the panoramic nature of CCDs (and the use …

UV Capabilities to Probe the Formation of Planetary Systems: From the ISM to Planets

Cernicharo, José; Gómez de Castro, Ana I.; Linsky, Jeffrey L. +2 more

Planetary systems are angular momentum reservoirs generated during star formation. Solutions to three of the most important problems in contemporary astrophysics are needed to understand the entire process of planetary system formation: The physics of the ISM. Stars form from dense molecular clouds that contain ∼ 30% of the total interstellar medi…

Structure and Evolution of White Dwarfs and their Interaction with the Local Interstellar Medium

Werner, K.; Barstow, M. A.

The development of far-UV astronomy has been particularly important for the study of hot white dwarf stars. A significant fraction of their emergent flux appears in the far-UV and traces of elements heavier than hydrogen or helium are, in general, only detected in this waveband or at shorter wavelengths that are also only accessible from space. Al…

A View to the Future: Ultraviolet Studies of the Solar System

Gérard, Jean-Claude; Brosch, Noah; Festou, Michel C. +1 more

We discuss the status of ultraviolet knowledge of Solar System objects. We begin with a short historical survey, followed by a review of knowledge gathered so far and of existing observational assets. The survey indicates that UV observations, along with data collected in other spectral bands, are necessary and in some cases essential to understan…

Ultraviolet Studies Of Interacting Binaries

Shore, Steven N.; Long, Knox S.; Marsh, Thomas R. +4 more

Interacting Binaries consist of a variety of stellar objects in different stages of evolution and those containing accreting compact objects still represent a major challenge to our understanding of not only close binary evolution but also of the chemical evolution of the Galaxy. These end-points of binary star evolution are ideal laboratories for…

Starbursts at space ultraviolet wavelengths

González Delgado, Rosa M.

Starbursts are systems with very high star formation rate per unit area. They are the preferred place where massive stars form; the main source of thermal and mechanical heating in the interstellar medium, and the factory where the heavy elements form. Thus, starbursts play an important role in the origin and evolution of galaxies. The similaritie…
