The PLATO mission [PDF]

open access: yes
PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large number of stars.

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 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.

Testing Lorentz symmetry with planetary orbital dynamics [PDF]

open access: yes, 2015
Planetary ephemerides are a very powerful tool to constrain deviations from the theory of General Relativity using orbital dynamics. The effective field theory framework called the Standard-Model Extension (SME) has been developed in order to ...

Absence of a metallicity effect for ultra-short-period planets [PDF]

open access: yes, 2017
Ultra-short-period (USP) planets are a newly recognized class of planets with periods shorter than one day and radii smaller than about 2 Earth radii.

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.

Constraining the Preferred-Frame $\alpha_1$, $\alpha_2$ parameters from Solar System planetary precessions

open access: yes, 2014
Analytical expressions for the orbital precessions affecting the relative motion of the components of a local binary system induced by Lorentz-violating Preferred Frame Effects (PFE) are explicitly computed in terms of the PPN parameters $\alpha_1 ...

NanoRocks: Design and Performance of an Experiment Studying Planet Formation on the International Space Station

open access: yes, 2017
In an effort to better understand the early stages of planet formation, we have developed a 1.5U payload that flew on the International Space Station (ISS) in the NanoRacks NanoLab facility between September 2014 and March 2016.
