Astrophysics datamining in the classroom: Exploring real data with new software tools and robotic telescopes

open access: yes, 2012
Within the efforts to bring frontline interactive astrophysics and astronomy to the classroom, the Hands on Universe (HOU) developed a set of exercises and platform using real data obtained by some of the most advanced ground and space observatories. The

Unexpected Near-Resonant and Metastable States of Young Multiplanet Systems

open access: yesThe Astrophysical Journal
Recent observations suggest that the incidence of near-resonant planets declines as planetary systems age, making young planetary systems key signposts of early dynamical evolution.

Clouds and Hazes in GJ 1214 b’s Metal-rich Atmosphere

open access: yesThe Astronomical Journal
The sub-Neptune GJ 1214 b has an infamously flat transmission spectrum, likely due to thick aerosols in its atmosphere. A recent JWST/MIRI spectroscopic phase curve of GJ 1214 b added to this picture, suggesting a highly reflective and metal-rich ...

Warm Jupiter Tidal Migration Can Spare Inner Planets; Hot Jupiter Tidal Migration May Not

open access: yesThe Astrophysical Journal
In this work, we investigate the dynamical survival of short-period inner planets during the high-eccentricity tidal migration of companion exterior giant planets.

Planet Mass Function around M Stars at 1–10 au: A Plethora of Sub-Earth Mass Objects

open access: yesThe Astrophysical Journal
Small planets (≲1 M _⊕ ) at intermediate orbital distances (∼1 au) represent an uncharted territory in exoplanetary science. The upcoming microlensing survey by the Nancy Grace Roman Space Telescope will be sensitive to objects as light as Ganymede and ...
