We report on H-band, ground-based observations of a transit of the hot Neptune GJ 436b. Once combined to achieve sampling equivalent to archived observations...
Limits to the presence of transiting circumbinary planets in CoRoT Data
Aims: During its flight phase, from 2007-2012, the CoRoT mission delivered light curves for over 2000 eclipsing binaries. Data from the Kepler mission have...
Line Shape Effects on Intensity Measurements of Solar Features: Brightness Correction to SOHO MDI Continuum Images
Continuum intensity observations obtained with the Michelson Doppler Imager (MDI) on board the SOHO mission provide long time series of filtergrams that are...
Lithium in the Hyades L5 brown dwarf 2MASS J04183483+2131275
Aims: From the luminosity, effective temperature and age of the Hyades brown dwarf 2MASS J04183483+2131275 (2M0418), substellar evolutionary models predict a...
Local Cosmology from Isolated Dwarfs: the derivation of star formation histories.
The color-magnitude diagram (CMD) is the most powerful tool to derive quantitative star formation histories (SFHs) of complex stellar systems which host...
Local Cosmology from Isolated Dwarfs: variable stars from the LCID project.
During Cycle 14 a total of 113 HST orbits were secured to observe five isolated dwarf galaxies, namely Tucana, LGS3, LeoA, IC1613, and Cetus. The aim of the...
LOFAR MSSS: detection of a low-frequency radio transient in 400 h of monitoring of the North Celestial Pole
We present the results of a four-month campaign searching for low-frequency radio transients near the North Celestial Pole with the Low-Frequency Array (LOFAR)...
Long-lasting activity of asteroid (248370) 2005 QN<SUB>173</SUB>
We present the results of observations of asteroid (248370) QN 173 obtained during July 2021-January 2022 with three telescopes. Our analysis revealed the...
Long-term photometric monitoring with the Mercator telescope. Frequencies and multicolour amplitudes of γ Doradus stars
Context: γ Dor stars are excellent targets for asteroseismology since the gravity modes present in these stars probe the deep stellar interiors. Mode...
