Abhishek Prakash (Caltech/IPAC) -- MIR Variability of WISE-Selected AGN in Stripe 82

Science Talk • 12:15 PM, December 11th, 2019 • Morrisroe LCR

We present a statistical analysis of the long-term mid-infrared variability for WISE-selected AGN over 270 square deg. of Sloan Stripe 82 field. AGN sample is selected using 3.4 and 4.6-micron channels of WISE and contains both obscured (Type-II) and unobscured (Type-I) AGN. We use WISE W1, and W2 single exposure (Level 1b) images to construct light curves for each of these AGN with typical baselines of ~8...

Alexander P. Stephan (UCLA) --- Stellar Evolution in Hierarchical Triples: Applications for Supermassive Black Holes and Exoplanets

Science Talk • 12:15 PM, December 18th, 2019 • Morrisroe 102 (Large Conference Room)

Hierarchical triples are widespread configurations of astrophysical systems, such as triple stars, binary stars orbiting SMBHs, or many planetary systems, among others. These systems are stable for long periods of time, allowing interesting dynamical effects, such as the Eccentric Kozai-Lidov mechanism, to occur. However, precisely because of the long-term stability of such systems, other physical effects can...

Andrew J. Rushby (UC Irvine): "Effects of Land Coverage and Host Star Spectral Energy Distribution on the Planetary Albedo of Terrestrial Worlds"

Science Talk • 12:15 PM, April 15th, 2020 • Morrisroe 102 (Large Conference Room)

The energy balance and climate of planets can be affected by the reflective properties of their land, ocean, and frozen surfaces. In this talk, I present results from several studies by our group at UC Irvine focussed on investigating the climates of terrestrial exoplanets orbiting M-dwarf stars. In particular, I will discuss the effect of host spectral energy distribution (SED) on the albedo of planetary...
