Validation of the WRF model for PWV forecasting at the Roque de los Muchachos Observatory
The atmospheric Precipitable Water Vapour content (PWV) is crucial for astronomical observations in the infrared. In this work, we have validated the Weather...
VAPHOT - A Package for Precision Differential Aperture Photometry
The aperture photometry package "vaphot" was developed to perform reliable and precise time-series photometry of uncrowded fields. This package works within the...
Variability in brown dwarfs: atmospheres and transits
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...
