Classifying Exoplanets with Gaussian Mixture Model [PDF]

, 2017
Recently, Odrzywolek and Rafelski (arXiv:1612.03556) have found three distinct categories of exoplanets, when they are classified based on density. We first carry out a similar classification of exoplanets according to their density using the Gaussian ...

On the survival of brown dwarfs and planets engulfed by their giant host star

, 2012
The recent discovery of two Earth-mass planets in close orbits around an evolved star has raised questions as to whether substellar companions can survive encounters with their host stars.

Observable Signatures of EMRI Black Hole Binaries Embedded in Thin Accretion Disks [PDF]

, 2011
We examine the electromagnetic (EM) and gravitational wave (GW) signatures of stellar-mass compact objects (COs) spiraling into a supermassive black hole (extreme mass-ratio inspirals or EMRIs), embedded in a thin, radiation-pressure dominated, accretion

Influence of the water content in protoplanetary discs on planet migration and formation

, 2016
The temperature and density profiles of protoplanetary discs depend crucially on the mass fraction of micrometre-sized dust grains and on their chemical composition.

Ground-breaking Exoplanet Science with the ANDES spectrograph at the ELT

, 2023
In the past decade the study of exoplanet atmospheres at high-spectral resolution, via transmission/emission spectroscopy and cross-correlation techniques for atomic/molecular mapping, has become a powerful and consolidated methodology.

The small and large lags of the elastic and anelastic tides. The virtual identity of two rheophysical theories

, 2015
The aim of this letter is to discuss the virtual identity of two recent tidal theories: the creep tide theory of Ferraz-Mello (Cel. Mech. Dyn. Astron. 116, 109, 2013) and the Maxwell model developed by Correia et al. (Astron. Astrophys.

Deep space experiment to measure $G$

, 2016
Responding to calls from the National Science Foundation (NSF) for new proposals to measure the gravitational constant $G$, we offer an interesting experiment in deep space employing the classic gravity train mechanism. Our setup requires three bodies: a

Preliminary bounds of the gravitational Local Position Invariance from Solar System planetary precessions

, 2013
In the framework of the Parameterized Post-Newtonian (PPN) formalism, we calculate the long-term Preferred Location (PL) effects, proportional to the Whitehead parameter $\xi$, affecting all the Keplerian orbital elements of a localized two-body system ...
