The preliminary results of the chemical analysis of a sample of 22 galactic R-stars with measured parallaxes are presented. We have derived the C/O and 12C/13C...

Spectroscopic studies of stars with and without planetary systems have concluded that planet hosts are more metal-rich. This enrichment is also seen in the...

We present a summary of main results from the studies performed in the series of papers The chemical composition of the Orion star forming region. We...

We report the results of our project devoted to study the chemical enrichment history of the field population in the Magellanic Clouds using Ca ii triplet...

The metallicity distribution of stars in the Fornax dwarf spheroidal galaxy is studied with infrared Ca II triplet spectroscopy for 117 red giants, obtained...

The CHilean Automatic Supernova sEarch (CHASE) project began in 2007 with the goal to discover young, nearby southern supernovae in order to (1) better...

Naruki gave an explicit construction of the moduli space of marked cubic surfaces, starting from a toric variety and proceeding with blow ups and contractions...
