The reduction of integral field spectroscopy (IFS) data requires several stages and many repetitive operations to convert raw data into, typically, a large number of spectra. Instead there are several semiautomatic data reduction tools and here we…

In this review I give a summary of the state of the art for what concerns the chemo-dynamical
numerical modelling of galaxies in general and of dwarf galaxies in particular. In particular, I
focus my attention on (i) initial conditions, (ii) the…

The perturbation caused by planet-moon binarity on the time-of-arrival
(TOA) signal of a pulsar with an orbiting planet is derived for the case of the
orbit of the planet-moon system inclined of an angle α with respect to
the plane…

We present spectroscopic and photometric observations of the emission-line star MWC 930 (V446 Sct) during its long-term optical brightening in 2006–2013. Based on our earlier data we suggested that the object has features found in Luminous Blue…

Gumbel’s first distribution is applied to smoothed monthly mean sunspot numbers for solar cycles 10 to 24. According to that, the next minimum for solar cycle 24-25 transition would be the deepest solar minimum of the last 150 years. This study…

We present 1.3 and 3.6 cm radio continuum images and a HCO+ spectrum of the massive star forming region G75.78+0.34 obtained with the Very Large Array (VLA) and with the Berkley Illinois Maryland Association (BIMA) interferometer. Three structures…

This paper reviews the major advances achieved in the Orion Nebula through the use of integral field spectroscopy (IFS). Since the early work of Vasconcelos and collaborators in 2005, this technique has facilitated the investigation of global…

An overview is presented of the recent advances in understanding the B[e] phenomenon among blue supergiant stars in light of high-angular resolution observations and with an emphasis on the results obtained by means of long baseline optical stellar…

We summarize the updated set of multiphase chemical evolution models
performed with 44 theoretical radial mass initial distributions and 10
possible values of efficiencies to form molecular clouds and stars. We
present the results about the infall…
