The Red Supergiant Progenitor of Type II Supernova 2024ggi

open access: yesThe Astrophysical Journal Letters
We present a detailed analysis of the progenitor and its local environment for the recently discovered Type II supernova (SN) 2024ggi at a distance of about 6.7 Mpc, by utilizing the pre-explosion images from the Hubble Space Telescope and Spitzer Space ...

Quantification of the Age Dependence of Mid-infrared Star Formation Rate Indicators

open access: yesThe Astrophysical Journal
We combine James Webb Space Telescope images of the nearby galaxy NGC 5194 in the hydrogen recombination line Pa α (1.8756 μ m) from the Cycle 1 program JWST-FEAST with 21 μ m dust continuum images from the Cycle 2 Treasury program JWGT to quantify the ...

Proto-Planetary Nebula with the Spitzer Space Telescope

open access: yes, 2010
The transition from Asymptotic Giant Branch star to Planetary Nebula is short-lived and mysterious. Though it lasts only a few thousand years, it is thought to be the time when the asymmetries observed in subsequent phases arise. During this epoch, the star is shrouded in thick clouds of dust and molecular gas; infrared observations are needed to ...

The HUSTLE Program: The UV to Near-IR Transmission Spectrum of the Hot Jupiter KELT-7b

open access: yesThe Astronomical Journal
The ultraviolet and optical wavelength ranges have proven to be a key addition to infrared observations of exoplanet atmospheres because they offer unique insights into the properties of clouds and hazes and are sensitive to signatures of disequilibrium ...

Modeling Spitzer 3.6 and 4.5 μm Eclipse Depths for the Inflated Hot Jupiter in the Evolved Binary System HD 202772

open access: yesThe Astronomical Journal
As an inflated hot Jupiter orbiting an early-type primary star in the evolved binary HD 202772 system, HD 202772 A b’s presence invites a study of how such a planet forms and evolves. As a prelude to potential atmospheric characterization with the latest
