Bridging the gap between stars and planets

Aina Palau, Dimitris Stamatellos, Matthew Bate +58

The formation mechanisms of brown dwarfs (BDs) and free-floating planets (FFPs) are poorly constrained. The two main competing scenarios include the star-like scenario, where these…

The Dynamics of Planetary Ejection

Malena Rice, William DeRocco, Sean N. Raymond

The ubiquity of free-floating planets inferred from microlensing and direct imaging surveys suggests that planetary ejection---a process in which planets initially born encircling…

Eliminating photon transport in long-baseline optical interferometry using quantum memories

Yousef K. Chahine, Chaohan Cui, William DeRocco +11

In this paper, we describe the fundamental operating mechanisms of optical interferometry using quantum memory and entanglement. We show how these remove the optical delay line bot…

The Persistent Missing Mass Problem in Planet Formation

Eve J. Lee, William DeRocco, Sam Hadden +1

Recent ground-based microlensing surveys suggest that our Galaxy may abound with small free floating planets, potentially up to 21 such planets per star. We explore the impli…

Predictions of the Nancy Grace Roman Space Telescope Galactic Exoplanet Survey. V. Detection Rates of Multiplanetary Systems in High Magnification Microlensing Events

Vito Saggese, Étienne Bachelet, Sebastiano Calchi Novati +34

The Nancy Grace Roman Space Telescope will expand the reach of gravitational microlensing surveys by increasing the number of events monitored and the precision of their light curv…

Are We There Yet? Challenges in Quantifying the Frequency of Earth Analogs in the Habitable Zone

Rachel B. Fernandes, Samson Johnson, Galen J. Bergsten +43

Searching for life elsewhere in the universe is one of the most highly prioritized pursuits in astronomy today. However, the ability to observe evidence of Earth-like life through…
