Hot Jupiters: Origins, Structure, Atmospheres

Journal of Geophysical Research: Planets, Volume 126, Issue 3, March 2021., 2021
Abstract We provide a brief review of many aspects of the planetary physics of hot Jupiters. Our aim is to cover most of the major areas of current study while providing the reader with additional references for more detailed follow‐up. We first discuss giant planet formation and subsequent orbital evolution via disk‐driven torques or dynamical ...

A Multiwavelength Classification and Study of Red Supergiant Candidates in NGC 6946

The Astrophysical Journal, 2023
We have combined resolved stellar photometry from Hubble Space Telescope (HST), Spitzer, and Gaia to identify red supergiant (RSG) candidates in NGC 6946, based on their colors, proper motions, visual morphologies, and spectral energy distributions.

Detection of the Buried Active Galactic Nucleus in NGC 6240 with the Infrared Spectrograph on the Spitzer Space Telescope [PDF]

SPIE Astronomical Telescopes + Instrumentation, 2004
We present mid-infrared spectra of the nearby ultraluminous infrared galaxy NGC 6240 taken with the Infrared Spectrograph (IRS) on the Spitzer Space Telescope. The spectrum of NGC 6240 is dominated by strong fine-structure lines, rotational H2 lines, and

The Nature and Origins of Sub‐Neptune Size Planets

Journal of Geophysical Research: Planets, Volume 126, Issue 1, January 2021., 2021
Abstract Planets intermediate in size between the Earth and Neptune, and orbiting closer to their host stars than Mercury does the Sun, are the most common type of planet revealed by exoplanet surveys over the last quarter century. Results from NASA's Kepler mission have revealed a bimodality in the radius distribution of these objects, with a relative

JWST Imaging of the Cartwheel Galaxy Reveals Dust Associated with SN 2021afdx

The Astrophysical Journal Letters, 2023
We present near- and mid-infrared (0.9–18 μ m) photometry of supernova (SN) 2021afdx, which was imaged serendipitously with the James Webb Space Telescope (JWST) as part of its Early Release Observations of the Cartwheel Galaxy.

Spitzer IRS Spectra of Optically Faint Infrared Sources with Weak Spectral Features [PDF]

, 2006
Spectra have been obtained with the low-resolution modules of the Infrared Spectrograph (IRS) on the Spitzer Space Telescope (Spitzer) for 58 sources having f$_{\nu}$(24 micron) > 0.75 mJy.

The SLUGGS survey: stellar masses and effective radii of early-type galaxies from Spitzer Space Telescope 3.6 μm imaging [PDF]

, 2016
Galaxy starlight at 3.6 μm is an excellent tracer of stellar mass. Here we use the latest 3.6 μm imaging from the Spitzer Space Telescope to measure the total stellar mass and effective radii in a homogeneous way for a sample of galaxies from the SAGES ...

GOALS-JWST: Unveiling Dusty Compact Sources in the Merging Galaxy IIZw096

The Astrophysical Journal Letters, 2022
We have used the Mid-InfraRed Instrument (MIRI) on the James Webb Space Telescope (JWST) to obtain the first spatially resolved, mid-infrared images of IIZw096, a merging luminous infrared galaxy (LIRG) at z = 0.036.

A survey of Karin cluster asteroids with the Spitzer Space Telescope [PDF]

Icarus, 2009
Abstract The Karin cluster is one of the youngest known families of main-belt asteroids, dating back to a collisional event only 5.8 ± 0.2 Myr ago. Using the Spitzer Space Telescope we have photometrically sampled the thermal continua (3.5–22 μm) of 17 Karin cluster asteroids of different sizes, down to the smallest members discovered so ...
