Planets around the K-giants BD+20 274 and HD 219415
We present the discovery of planet-mass companions to two giant stars by the ongoing Penn State-Toruń Planet Search conducted with the 9.2 m Hobby-Eberly...
Planets observed with CHEOPS. Two super-Earths orbiting the red dwarf star TOI-776
Context. M-dwarf stars are the most common of potential exoplanet host stars in the Galaxy. It is therefore very important to understand planetary systems...
Planets, candidates, and binaries from the CoRoT/Exoplanet programme. The CoRoT transit catalogue
The CoRoT space mission observed 163 665 stars over 26 stellar fields in the faint star channel. The exoplanet teams detected a total of 4123 transit-like...
Plaskett's star: analysis of the CoRoT photometric data
Context. The second short run (SRa02) of the CoRoT space mission for asteroseismology was partly devoted to stars belonging to the Mon OB2 association. An...
Plasma Jets and Eruptions in Solar Coronal Holes: A Three-dimensional Flux Emergence Experiment
A three-dimensional (3D) numerical experiment of the launching of a hot and fast coronal jet followed by several violent eruptions is analyzed in detail. These...
PLATO as it is : A legacy mission for Galactic archaeology
Deciphering the assembly history of the Milky Way is a formidable task, which becomes possible only if one can produce high-resolution chrono-chemo-kinematical...
Pleiades low-mass brown dwarfs: the cluster L dwarf sequence
Aims.We present a search for low-mass brown dwarfs in the Pleiades open cluster. The identification of Pleiades members fainter and cooler than those currently...
Context. Spectra of planetary nebulae (PNe) are characterised by strong forbidden emission lines and often also by an infrared (IR) excess. A few PNe show dust...
