We review briefly the observational understanding of emergence of flux in both the quiet Sun and active regions in the light of first results from the joint...

We present here a part of the project aimed to study the SFH in different parts of the SMC. We observed 12 fields during a four year campaign (2001-2004) using...

In the framework of a long-term program aimed at studying stellar populations in the Carina dSph galaxy, we present the photometric calibration of the two...

The spectroscopic parallaxes in the Hipparcos catalogue can be used to translate absolute stellar fluxes observed at Earth to the fluxes emerging at the stellar...

Cyg OB2 No. 5 (BD+40deg4220; V729 Cyg) is known to be a contact binary system formed by two O-type stars. For this object a 6-cm radio emission has been...

HIRES will be the high-resolution spectrograph at optical and near-infrared (NIR) wavelengths for ESO's Extremely Large Telescope (ELT). It will consist of...

The current instrumentation plan for the E-ELT foresees a High Resolution Spectrograph conventionally indicated as HIRES. Shaped on the study of extra-solar...

I describe how the principles of lexicography have been applied in limited ways in astronomy and look at the revision work under way for the third edition of...

A brief narrative on how the effective radius and isophotal diameters were accepted as galaxy size measures is presented. Evidence suggests that these...
