Twinkle Twinkle Little Star, Roman Sees Where You Are: Predicting Exoplanet Transit Yields in the Rosette Nebula with the Nancy Grace Roman Space Telescope

The Astronomical Journal
Young stars host only a small fraction of the known exoplanet population because their photometric variability, magnetic activity, and frequent placement in dense, poorly resolved regions hamper exoplanet detections.

Influence of Modeling Assumptions on the Inferred Dynamical State of Resonant Systems: A Case Study of the HD 45364 System

The Astrophysical Journal
Planetary systems exhibiting mean motion resonances (MMRs) offer unique opportunities to study the imprint of disk-induced migration on the orbital architectures of planetary systems. The HD 45364 system, discovered via the radial velocity (RV) method to

Interlíngua: miscigenação linguística e ficção poética

MatLit, 2015
This article addresses the issue of inter-language in the contemporary situation, a process of relationship among languages, caused mostly by mobility, migration, nomadism, war, globalization, colonization, exile and, more recently, digital ...

TILTING JUPITER (A BIT) AND SATURN (A LOT) DURING PLANETARY MIGRATION [PDF]

, 2015
We study the effects of planetary late migration on the gas giants ’ obliquities. We consider the planetary instability models from Nesvorný and Morbidelli, in which the obliquities of Jupiter and Saturn can be excited when spin– orbit resonances occur ...

Exomoons of Circumbinary Planets

The Astrophysical Journal
Confirmation of the first exomoon remains elusive. Although several exomoon candidates exist around single stars, there are currently no candidates around circumbinary planets (CBPs).

The influence of hypothetical exomoons on planetary thermal phase curves

Astronomy & Astrophysics
Context. More than 200 moons exist in our Solar System, yet no exomoon has been confirmed to date. While the innermost two planets of the Solar System lack natural satellites and most studies favour the existence of exomoons around long-period planets ...

The Relative Cold-trapping Likelihood of Water on Airless Rocky Bodies

The Planetary Science Journal
Many planetoids are airless, but despite the lack of a collisional atmosphere, these bodies can experience volatile migration toward the polar regions via the exosphere.

Asteroid families and their relation to planetary migration [PDF]

, 2013
In this thesis, we study how the planetary migration affects asteroid families. We identify the families among the Trojans of Jupiter by analysing their properties in the space of resonant elements, the size-frequency distribution and the colour indices.
