Outcomes of Grazing Impacts Between Sub-Neptunes in Kepler Multis

Jason Hwang, Sourav Chatterjee, James Lombardi +2

Studies of high-multiplicity, tightly-packed planetary systems suggest that dynamical instabilities are common and affect both the orbits and planet structures, where the compact o…

Dynamics and Collisional Evolution of Closely Packed Planetary Systems

Jason A. Hwang, Jason H. Steffen, James C. Lombardi +1

High-multiplicity Kepler systems (referred to as Kepler multis) are often tightly packed and may be on the verge of instability. Many systems of this type could have experienced pa…

The period ratio distribution of Kepler's candidate multiplanet systems

Jason H. Steffen, Jason A. Hwang

We calculate and analyze the distribution of period ratios observed in systems of Kepler exoplanet candidates including studies of both adjacent planet pairs and all planet pairs.…

An Assessment of the Energy Budgets of Low-Ionization Nuclear Emission Regions

Michael Eracleous, Jason A. Hwang, Helene M. L. G. Flohic

Using the SEDs of the weak AGNs 35 LINERs presented in a companion paper, we assess whether photoionization by the weak AGN can power the emission-line luminosities measured throug…

Spectral Energy Distributions of Weak Active Galactic Nuclei Associated With Low-Ionization Nuclear Emission Regions

Michael Eracleous, Jason A. Hwang, Helene M. L. G. Flohic

We present a compilation of spectral energy distributions of 35 weak AGNs in LINERs using recent data from the published literature. We make use of previously published compilation…
