Eight luminous early-type galaxies in nearby pairs and sparse groups I. Stellar populations spatially analysed
D. A. Rosa, A. C. Milone, A. C. Krabbe +1
We present a detailed spatial analysis of stellar populations based on long-slit optical spectra in a sample of eight luminous early-type galaxies selected from nearby sparse group…
Two semi-automated computational approaches for spectroscopic analysis of stellar photospheres: detailed characterization at high resolution and abundance determination at medium resolution
Andre Milone, Ronaldo da Silva, Anne Sansom +1
We report on two distinct computational approaches to self-consistently measure photospheric properties of large samples of stars. Both procedures consist of a set of several semi-…
Accurate and homogeneous abundance patterns in solar-type stars of the solar neighbourhood: a chemo-chronological analysis
R. da Silva, G. F. Porto de Mello, A. C. Milone +3
We report the abundances of C, Na, Mg, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Zr, Ba, Ce, Nd, and Sm in 25 solar-type stars in the solar neighbourhood, and their cor…
SPARC4: A Simultaneous Polarimeter and Rapid Camera in 4 Bands
C. V. Rodrigues, F. J. Jablonski, K. Taylor +13
We present the basic concept of a new astronomical instrument: SPARC4 - Simultaneous Polarimeter and Rapid Camera in 4 bands. SPARC4 combines in one instrument: (i) photometric and…
Element abundances in the stars of the MILES spectral library: the Mg/Fe ratio
Andre de Castro Milone, Anne E. Sansom, Patricia Sanchez-Blazquez
We have obtained [Mg/Fe] measurements for 76.3% of the stars in the MILES spectral library used for understanding stellar atmospheres and stellar populations in galaxies and star c…
Homogeneous photospheric parameters and C abundances in G and K nearby stars with and without planets
Ronaldo Da Silva, Andre C. Milone, Bacham E. Reddy
We present a determination of photospheric parameters and C abundances for a sample of 172 G and K dwarfs, subgiants, and giants with and without detected planets in the solar neig…
