C III] Imagery of Planetary Nebulae and Extragalactic H II Regions
We report the first results of a Cycle 12 Hubble Space Telescope SNAP program imaging the C III] 1909Å lines in planetary nebulae (PNe) and extragalactic H II...
C/O and N/O ratios in planetary nebulae with [WC] central stars
Planetary nebulae (PNe) around [WR] central stars (WRPNe) constitute a particular photoionized nebula class, representing about 10-15% of the PNe with known...
C/O vs Mg/Si ratios in solar-type stars: The HARPS sample
The determination of the chemical composition of extrasolar planets has been the subject of numerous studies in the last years. While the composition of the...
CAFÉ-BEANS: An exhaustive hunt for high-mass binaries
CAFÉ-BEANS is an on-going survey running on the 2.2 m telescope at Calar Alto. For more than two years, CAFÉ-BEANS has been collecting high-resolution spectra...
CaII triplet in Sextans dSph galaxy (Battaglia+, 2011)
The spectroscopic observations were carried out at VLT/FLAMES between 2003 and 2004, with the exception of one pointing which was re-observed in 2008 May...
CaII triplet of RGB from VLT/FLAMES obs. (Battaglia+, 2008)
The data sets presented here were collected between 2003 August and 2005 November. They consist of 15 pointings in the Sculptor dSph and 11 in the Fornax dSph...
