We present the results of a study of the stellar activity in the solar neighborhood using complete kinematics (galactocentric velocities U, V, W) and the...

Mostly multiband photometric transit observations have been used so far to retrieve broadband transmission spectra of transiting exoplanets in order to study...

We present simultaneous two-dimensional spectroscopy of the circumnuclear region (12" x 9") of the galaxy NGC 7331, obtained with an optical fiber system...

Integral field spectroscopy in the central 16''x 12'' (2.4 kpc x 1.8 kpc, if H0 = 75 km s-1 Mpc-1) of the Seyfert 1.9 galaxy NGC 2992 has been obtained using...

We present bidimensional spectroscopy of the central region (9."4 x 12."2) of the Seyfert galaxy NGC 3516 in the two spectral ranges 4186-5839 A and 6110-7890 A...

The first detailed chemical abundance analysis of the M-dwarf (M4.0) exoplanet-hosting star Ross 128 is presented here, based upon near-infrared (1.5–1.7 μm)...

In this paper, we intend to explain the behaviour of the evolved double-lined eclipsing binary TZ Fornacis on the basis of tidal evolution derived from standard...

We have re-analyzed the Galactic O-star sample from citet{puls96} by means of line-blanketed NLTE model atmospheres in order to investigate the influence of...
