Context. The sample of hot Jupiters that have been studied in great detail is still growing. In particular, when the planet transits its host star, it is...
A photometric study of the light variations of the triple system DG Leo
Multi-site and multi-year differential photometry of the triple star DG Leo reveals a complex frequency spectrum that can be modelled as the combination of at...
A planetary system with two transiting mini-Neptunes near the radius valley transition around the bright M dwarf TOI-776
We report the discovery and characterization of two transiting planets around the bright M1 V star LP 961-53 (TOI-776, J = 8.5 mag, M = 0.54 ± 0.03 M ☉)...
A plausible link between dynamically unsettled molecular gas and the radio jet in NGC 6328
We report the detection of outflowing molecular gas at the center of the nearby radio galaxy NGC6328 (z = 0.014), which has a gigahertz-peaked spectrum radio...
A polarization model for the German Vacuum Tower Telescope from in situ and laboratory measurements
It is essential to properly calibrate the polarimetric properties of telescopes, if one wants to take advantage of the capabilities of high precision spectro...
A very rapid swing in the polarization position angle (PA) in the optical region was observed in blazar OJ 287 during one night of our five nights UBVRI...
A precise architecture characterization of the π Mensae planetary system★
Context. The bright star π Men was chosen as the first target for a radial velocity follow-up to test the performance of ESPRESSO, the new high-resolution...
A prediction about the age of thick discs as a function of the stellar mass of the host galaxy
One of the suggested thick disc formation mechanisms is that they were born quickly and in situ from a turbulent clumpy disc. Subsequently, thin discs formed...
This paper announces the release at CDS of a substantial set of point sources detected by the DENIS project. DENIS is the first astronomical survey of the...
