Reinterpretation of Tractus Fossae region as an asymmetric rift system on Mars
(Academic Press Inc Elsevier Science, 2008-12)
The Tractus Fossae region of Mars is a wide area dominated by grabens, normal faults and pit crater chains. In this work, based on previous studies on the area and the new interpretation of topographic data and morphological ...
The mysterious age invariance of the planetary nebula luminosity function bright cut-off
(Springer Nature, 2018-06)
Planetary nebulae mark the end of the active life of 90% of all stars. They trace the transition from a red giant to a degenerate white dwarf. Stellar models predicted that only stars above approximately twice the solar ...

Planet heating prevents inward migration of planetary cores
(Nature Publishing Group, 2015-04)
Planetary systems are born in the disks of gas, dust and rocky fragments that surround newly formed stars. Solid content assembles into ever-larger rocky fragments that eventually become planetary embryos. These then ...
The eccentricity distribution of giant planets and their relation to super-Earths in the pebble accretion scenario
(2020-11-01)
Observations of the population of cold Jupiter planets (r >1 AU) show that nearly all of these planets orbit their host star on eccentric orbits. For planets up to a few Jupiter masses, eccentric orbits are thought to be ...
Dust and gas in the disk of HL TAURI: surface density, dust settling, and dust-to-gas ratio
(IOP Publishing, 2016)
The recent ALMA observations of the disk surrounding HL Tau reveal a very complex dust spatial distribution. We present a radiative transfer model accounting for the observed gaps and bright rings as well as radial changes ...
