Large sub-Neptunes are uncommon around the coolest stars in the Galaxy and are rarer still around those that are metal-poor. However, owing to the large planet-to-star radius ratio, these planets are highly suitable for atmospheric study via transmis

Context. EE Cep is one of few eclipsing binary systems with a dark, dusty disk around an invisible object similar to {\epsilon} Aur. The system is characterized by grey and asymmetric eclipses every 5.6 yr, with a significant variation in their photo

P., Palle, E., Pepe, F., Queloz, D., Ségransan, D., Udry, S., Wilson, P. A.

We report the discovery of two transiting planetary systems: a super dense, sub-Jupiter mass planet WASP-86b (\mpl\ = 0.82 $\pm$ 0.06 \mj, \rpl\ = 0.63 $\pm$ 0.01 \rj), and a bloated, Saturn-like planet WASP-102b (\mpl\ = 0.62 $\pm$ 0.04 \mj, \rpl\=1

A Semi-automatic Search for Giant Radio Galaxy Candidates and their Radio-Optical Follow-up

Autor: Santiago-Bautista, I. del C., Rodriguez-Rico, C. A., Andernach, H., Coziol, R., Torres-Papaqui, J. P., Andrade, E. F. Jimenez, Plauchu-Frayn, I., Momjian, E.

We present results of a search for giant radio galaxies (GRGs) with a projected largest linear size in excess of 1 Mpc. We designed a computational algorithm to identify contiguous emission regions, large and elongated enough to serve as GRG candidat

A mid infrared study of low-luminosity AGNs with WISE

Autor: Coziol, R., Torres-Papaqui, J. P., Plauchu-Frayn, I., Andernach, H., Neri-Larios, D. M., Ortega-Minakata, R. A., Islas-Islas, J. M.

Using data from the Wide-field Infrared Survey Explorer (WISE) we show that the mid infrared (MIR) colors of low-luminosity AGNs (LLAGNs) are significanlty different from those of post-asymptotic giant branch stars (PAGBs). This is due to a differenc
