The atmospheric Precipitable Water Vapour content (PWV) is crucial for astronomical observations in the infrared. In this work, we have validated the Weather...

The aperture photometry package "vaphot" was developed to perform reliable and precise time-series photometry of uncrowded fields. This package works within the...

We have obtained series of continuous differential photometry in the J and KS bands for several L-type dwarfs. We intend to search for photometric variability...

Variability is a key property of ultracool dwarfs as it may induce physical noise that limits the accuracy of radial velocities. In this paper we report on our...

We present preliminary results of a 4-month campaign carried out in the framework of the Mons project, where time-resolved Hα observations are used to study the...

We compile a database of physical parameters for the sample stars from the literature and new ground-based observations. We analyse the Kepler light curve of...

We have obtained series of images in the near infrared J and Ks bands for seven L-type dwarfs with a duration of 3 to 6 hours. We present results on: 1) the...
