Context. Our knowledge of the intrinsic parameters of exoplanets is as precise as our determinations of their stellar hosts parameters. In the case of radial...

PublicationThe Penn State-Toruń Centre for Astronomy Planet Search stars. I. Spectroscopic analysis of 348 red giants
Aims: We present basic atmospheric parameters (Teff, log g, vt, and [Fe/H]) as well as luminosities, masses, radii, and absolute radial velocities for 348 stars...

PublicationThe PEP survey: clustering of infrared-selected galaxies and structure formation at z ˜ 2 in GOODS-South
This paper presents the first direct estimate of the 3D clustering properties of far-infrared sources up to z˜ 3. This has been possible thanks to the PACS...

PublicationThe persistent activity of Jupiter-family comets at 3–7 AU
We analyze the activity of 89 comets observed with the Spitzer Space Telescope.We conclude that at least 24% of Jupiter-family comets are active at 3–7 AU...

PublicationThe Phantom Dark Matter Halos of the Local Volume in the Context of Modified Newtonian Dynamics
We explore the predictions of Milgromian gravity (MOND) in the local universe by considering the distribution of the "phantom" dark matter (PDM) that would...

PublicationThe phase function for stellar acoustic oscillations - III. The solar case
The effects of uncertainties in the structure of the superficial layers of the Sun, such as the helium abundance, opacity and equation of state, on the p-mode...

PublicationThe phase function for stellar acoustic oscillations - IV. Solar-like stars
In recent years there has been some progress towards detecting solar-like oscillations in stars. The goal of this challenging project is to analyse frequency...

PublicationThe phase function for stellar acoustic oscillations. I - Theory
The influence of the upper layers of a star on p-mode frequencies can be described asymptotically by means of a phase function, which depends essentially only...

PublicationThe phase function for stellar acoustic oscillations. II - Effects of filtering
Frequencies of solar acoustic oscillations can be analyzed asymptotically in terms of a function determined by the sound speed in the bulk of the sun and a...
