OTELO Survey: Optimal Emission-Line Flux Determination with OSIRIS/GTC
Emission-line galaxies are important targets for understanding the chemical evolution of galaxies in the universe. Deep, narrowband imaging surveys allow...
An attempt is made to find the zodiacal cloud shape out of the ecliptic, on the basis of the Mujica et al (1980) establishment of the optical homogeneity of the...
Outburst activity in comets - II. A multiband photometric monitoring of comet 29P/Schwassmann-Wachmann 1
We have carried out a continuous multiband photometric monitoring of the nuclear activity of comet 29P/Schwassmann-Wachmann 1 from 2008 to 2010. Our main aim...
Outbursts on normal stars. FH Leo misclassified as a novalike variable
We present high resolution spectroscopy of the common proper motion system FH Leo (components HD 96273 and BD+07 2411B), which has been classified as a novalike...
Outcome of Six Candidate Transiting Planets from a TrES Field in Andromeda
Driven by the incomplete understanding of the formation of gas giant extrasolar planets and of their mass-radius relationship, several ground-based, wide-field...
