Light elements are important tracers of the internal stellar structure and kinematics. Li and Be are both burned in the stellar interiors but Be requires much...
Light pollution generated by laser guide star at Canarian Observatories
A new generation of instrument using a launching laser is been developed to correct the atmospheric image blurring and to establish optical communication with...
There are some networks of SQM photometers that provide measures of the night sky brightness every night. The analysis of the data provided by the photometers...
Trojan asteroids are an interesting population of minor bodies due to their dynamical characteristics, their physical properties and that they are relatively...
Lightcurve and Phase Function Photometry of the OSIRIS-REx Target (101955) 1999 RQ36
We present visible wavelength photometry of the OSIRIS-REx target asteroid (101955) 1999 RQ36. We find a rotation period of 4.2968 ± 0.0017 hr and phase slope...
In this paper, we use information from the light field to obtain a distribution map of the wavefront phase. This distribution is associated with changes in...
