The high activity of 3C 454.3 in autumn 2007. Monitoring by the WEBT during the AGILE detection
C. M. Raiteri, M. Villata, W. P. Chen +5
The quasar-type blazar 3C 454.3 underwent a phase of high activity in summer and autumn 2007, which was intensively monitored in the radio-to-optical bands by the Whole Earth Blaza…
The WEBT Campaign on the Blazar 3C279 in 2006
M. Boettcher
The quasar 3C279 was the target of an extensive multiwavelength monitoring campaign from January through April 2006, including an optical-IR-radio monitoring campaign by the Whole…
Physical parameters of evolved stars in clusters and in the field from line-depth ratios
K. Biazzo, L. Pasquini, A. Frasca +6
We present a high-resolution spectroscopic analysis of two samples of evolved stars selected in the field and in the intermediate-age open cluster IC 4651, for which detailed measu…
Deriving temperature, mass and age of evolved stars from high-resolution spectra. Application to field stars and the open cluster IC 4651
K. Biazzo, L. Pasquini, L. Girardi +6
We test our capability of deriving stellar physical parameters of giant stars by analysing a sample of field stars and the well studied open cluster IC 4651 with different spectros…
Spectroscopic Data Analysis for Precise Determination of Stellar Temperatures
K. Biazzo, A. Frasca, S. Catalano +1
The ratio of the depths of spectral lines is a powerful indicator of the effective temperature. The method based on this analysis is capable of discerning small temperature variati…
Photospheric temperature measurements in young main sequence stars
K. Biazzo, A. Frasca, G. W. Henry +2
As part of our program to study stellar photospheric and chromospheric activity, we have examined several young solar type stars with activity levels intermediate between the Sun a…
