SN 1987A at the end of its second decade

Karina Kjaer, Per Groeningsson, Rubina Kotak +2

After nearly two decades at least five emission mechanisms can be found in SN 1987A. The ejecta continue to glow as a result of the radioactive decay of long-lived nuclei (mostly 4…

Periodic radial velocity variations in RU Lupi

H. C. Stempels, G. F. Gahm, P. P Petrov

Context. RU Lup is a Classical T Tauri star with unusually strong emission lines, which has been interpreted as manifestations of accretion. Recently, evidence has accumulated that…

The Peculiar Type Ia Supernova 2005hk

V. Stanishev, S. Taubenberger, G. Blanc +15

We present a preliminary analysis of an extensive set of optical observations of the Type Ia SN 2005hk. We show that the evolution of SN 2005hk closely follows that of the peculiar…

Reconstructing the Thomson Optical Depth due to Patchy Reionization with 21-cm Fluctuation Maps

Gilbert Holder, Ilian T. Iliev, Garrelt Mellema

Large fluctuations in the electron column density can occur during the reionization process. We investigate the possibility of deriving the electron density fluctuations through de…

Dynamical masses of two young globular clusters in the blue compact galaxy ESO 338-IG04

Goran Ostlin, Robert J. Cumming, Nils Bergvall

We present high-resolution echelle spectroscopy, obtained with the UVES spectrograph on ESO/VLT, of two luminous star clusters in the metal-poor blue compact galaxy ESO 338-IG04 at…

Spitzer measurements of atomic and molecular abundances in the Type IIP SN 2005af

Rubina Kotak, Peter Meikle, Monica Pozzo +12

We present results based on Spitzer Space Telescope mid-infrared (3.6-30 micron) observations of the nearby IIP supernova 2005af. We report the first ever detection of the SiO mole…
