Circumstellar Envelopes as AGB Mass-Loss Signatures
Low- and intermediate-mass stars (1--8 M&sun;) lose up to 80 % of their initial mass during the Asymptotic Giant Branch (AGB) phase. Heavy mass loss is the...
Circumstellar PAHs in IRAS 16594-4656: a new proto-planetary nebula with a strong 21mum dust feature
Based on ISO SWS+LWS observations, we identify IRAS 16594-4656 as a new member of the rare class of C-rich proto-planetary nebulae with the 21 μm dust feature...
CLASP2: The Chromospheric LAyer Spectro-Polarimeter
We present the instrument, science case, and timeline of the CLASP2 sounding rocket mission. The successful CLASP (Chromospheric Lyman-Alpha Spectro-Polarimeter...
CLASP: A UV Spectropolarimeter on a Sounding Rocket for Probing theChromosphere-Corona Transition Regio
The wish to understand the energetic phenomena of the outer solar atmosphere makes it increasingly important to achieve quantitative information on the magnetic...
Classification and vsini of Vega-type and PMS stars (Mora+, 2001)
File table1.dat contains the log of the spectroscopic observations of the stars in the EXPORT sample taken with the Isaac Newton Telescope during the 1998...
Classification of Galaxies by Their Radial Profiles: Unbarred Early Types
We classify 46 broad band surface-brightness profiles in the visible from a sample of nearby early-type unbarred galaxies imaged at the ING (La Palma) and in...
