In the diffusion-collision model, the unfolding or backward rates are given by the likelihood of secondary structural cluster dissociation. In this work, we introduce a backward rate calculation modeled from a Kramers-type thermal tunneling through a barrier, which represents the free energy potential well for buried hydrophobic residues. Our

In a previous study, Virtual Observatory tools were used to cross-match the IPHAS catalogue with the 2MASS catalogue for searching young very low-mass objects. We defined photometric criteria to identify Halpha emission sources with near-infrared colors similar to known young very low-mass stars and brown dwarfs. Spectral types have been derived

Two interesting case studies of pulsating components in triple systems are highlighted in this presentation. We first report on the new results of a detailed study of the double-lined spectroscopic-visual system DG Leonis based on recent photometric and high-resolution spectroscopic data. This triple system has two components showing mild Am

Photometric observations in the VRcIc bands spanning the time interval between 2004 September 22 and 2010 November 23 were performed with six instruments on five telescopes. Most of the data were obtained with the 60/90/180cm Schmidt telescope of the Konkoly Observatory, equipped with a Photometric AT 200 camera, and with the 1-m Ritchey-Chretien-

EMIR is the near-infrared wide-field camera and multi-slit spectrograph being built for Gran Telescopio Canarias. We present here the work being done on its data processing pipeline. PyEmir is based on Python and it will process automatically data taken in both imaging and spectroscopy mode. Part of the PyEmir code can be reused by other GTC

Based on drizzled F606W and F814W images, we present quantitative structural parameters in the V-band rest-frame for all galaxies with z < 1 and I814(AB) < 24.5 mag in the Hubble Deep Fields North and South. Our structural parameters are based on a two-component surface brightness distribution using a Sérsic bulge and an exponential disc. Detailed
