    A Hubble View of Star Forming Regions in the Magellanic Clouds

    The Magellanic Clouds (MCs) offer an outstanding variety of young stellar associations, in which large samples of low-mass stars (with M≲1 M⊙ currently in the act of formation can be resolved and explored in deta...

    The Need for Ultraviolet to Understand the Chemical Evolution of the Universe and Cosmology.

    We identify an important set of key areas where an advanced observational Ultraviolet capability would have major impact on studies of cosmology and Galaxy formation in the young Universe. Most of these are as...

    Detecting Primordial Stars

    We discuss the expected properties of the first stellar generations in the Universe. We find that it is possible to discern truly primordial populations from the next generation of stars by measuring the metal...

    The Initial Conditions Tostar Formation: Lowmass Stars at Lowmetallicity

    We have measured the present accretion rate of roughly 800 low-mass (∼ 1 . 1.4 M⊙) pre-Main Sequence stars in the field of SN 1987A in the Large Magellanic Cloud.

    Radio Observations of γ-Ray Burst Afterglows

    Since 1997 the afterglow of γ-ray bursting sources (GRBs) has occasionally been detected in the radio, as well in other wavelengths bands. In particular, the interesting and unusual γ-ray burst GRB980425, thou...

    Ultraviolet Supernovae

    The observations of supernovae made with IUE and HST are reviewed and discussed. The various supernova types are characterized and discussed in the light of their ultraviolet properties. Special emphasis is place...

    T Tauri Stars in the Large Magellanic Cloud: A Combined HST and VLT Effort

    The combination of the unprecedented spatial resolution attainable with WFPC2 on board HST and of the large collecting area of the VLT makes it possible to study in detail the low mass pre-Main Sequence stars ...

    IUE Observations of Supernovae

    The launch of the International Ultraviolet Explorer (IUE) satellite in early 1978 marked the beginning of a new era for SN studies because of its capability of measuring the ultraviolet emission of objects as...

    A Supernova with a Difference, SN 1986J

    A new radio source was discovered on 21 August 1986 by VAN GORKOM et al. [1] during their study of the nearby, edge-on, spiral galaxy NGC891. Because the source lay in the disk and had HI absorption features c...

    On the Nature of Type Ib Supernova Progenitors

    The realization that there is a separate subclass of Type I supernovae (SNe) to be denoted as Type Ib came after the detailed study of the SN 1983N in M83 (PANAGIA et al [1]; see also PANAGIA [2], WHEELER and LEV...

    A Third, Inner Light Echo Ring Around SN 1987A

    At the beginning of this year evidence has been found for a third, inner echo near SN 1987A (BOND et al. [l]). This discovery is of great importance because the detection of an echo so close to the SN 1987A revea...

    Type Ib supernovae: What they may be and what they are not

    We show that the progenitors of Type Ib supernovae are likely to be moderately massive stars (M ∼ 7 M⊙) in binary systems and we argue that the hypothesis that they originate from very massive stars (M > 20 M⊙) i...

    Ultraviolet observations of SN 1987A

    The results of IUE observations of- SN 1987A are presented and discussed. One of the most important conclusions is that the direct progenitor of the supernova was a blue supergiant (Sk -69 202) that, however, ...

    The accretion of interstellar matter by white dwarfs

    The problem of the energy released by interstellar matter in its accretion by low-luminosity stars is examined. It is found that nearly all the gravitational energy is available as the energy source for the ac...
