Spots, plages, and flares on lambda Andromedae and II Pegasi
A. Frasca, K. Biazzo, G. Tas +2
We present the results of a contemporaneous photometric and spectroscopic monitoring of lambda And and II Peg aimed at investigating the behavior of surface inhomogeneities in the…
Effective temperature vs line-depth ratio for ELODIE spectra. Gravity and rotational velocity effects
K. Biazzo, A. Frasca, S. Catalano +1
The dependence on the temperature of photospheric line-depth ratios (LDRs) in the spectral range 6190-6280 A is investigated by using a sample of 174 ELODIE Archive stellar spectra…
Seismology of Procyon A: determination of mode frequencies, amplitudes, lifetimes, and granulation noise
S. Leccia, H. Kjeldsen, A. Bonanno +3
The F5 IV-V star Procyon A (aCMi) was observed in January 2001 by means of the high resolution spectrograph SARG operating with the TNG 3.5m Italian telescope (Telescopio Nazionale…
Simulating Galaxy Clusters - III: Properties of the Intracluster Stars
J. Sommer-Larsen, A. D. Romeo, L. Portinari
Cosmological (LCDM) TreeSPH simulations of galaxy clusters have been performed, invoking star-formation, chemical evolution with non-instantaneous recycling, metal dependent radiat…
Noncommutative Synchrotron
P. Castorina, A. Iorio, D. Zappala
We study the departures from the classical synchrotron radiation due to noncommutativity of coordinates. We find that these departures are significant, but do not give tight bounds…
