Radiative Transfer and Inversion codes for characterizing planetary atmospheres: an overview

open access: yes, 2023
The study of planetary atmospheres is crucial for understanding the origin, evolution, and processes that shape celestial bodies like planets, moons and comets.

Orbital motions and the conservation-law/preferred-frame $\alpha_3$ parameter [PDF]

open access: yes, 2014
We analytically calculate some orbital effects induced by the Lorentz-invariance/momentum-conservation PPN parameter $\alpha_3$ in a gravitationally bound binary system made of a compact primary orbited by a test particle.

Three Small Planets Transiting a Hyades Star [PDF]

open access: yes, 2018
We present the discovery of three small planets transiting K2-136 (LP 358 348, EPIC 247589423), a late K dwarf in the Hyades. The planets have orbital periods of $7.9757 \pm 0.0011$, $17.30681^{+0.00034}_{-0.00036}$, and $25.5715^{+0.0038}_{-0.0040 ...

The Case for a Deep Search for Earth's Trojan Asteroids [PDF]

open access: yesNature Astronomy, 3, 193-194 (2019), 2019
The existence of Earth's Trojan asteroids is not well constrained and represents a major gap in our inventory of small bodies in near-Earth space. Their discovery would be of high scientific and human interest.

ESA-Ariel Data Challenge NeurIPS 2022: Inferring Physical Properties of Exoplanets From Next-Generation Telescopes [PDF]

open access: yes, 2022
The study of extra-solar planets, or simply, exoplanets, planets outside our own Solar System, is fundamentally a grand quest to understand our place in the Universe.

High-contrast imaging study of exoplanets and circumstellar disks [PDF]

open access: yes, 2023
High-contrast imaging provides an excellent tool to detect and characterise exoplanets and circumstellar disks. Understanding the connection between them is key for the improvement of planet formation and evolution theories.

Thermal decomposition as an activity driver of near-Earth asteroid (3200) Phaethon

open access: yes, 2022
Near-Earth asteroid (3200) Phaethon is an active asteroid with a dust tail repeatedly observed over the past decade for 3 days during each perihelion passage down to a heliocentric distance of 0.14 au. The mechanism causing the activity is still debated,

Enhancing the Google imagery using a wavelet filter [PDF]

open access: yes, 2010
In some previous papers we proposed the use of free software for a processing of the Google satellite imagery. Here we discuss the use of a wavelet filter for the same purposes.

The production of proton-rich isotopes beyond iron: The ?-process in stars [PDF]

open access: yes, 2016
© 2016 World Scientific Publishing Company. Beyond iron, a small fraction of the total abundances in the Solar System is made of proton-rich isotopes, the p-nuclei.
