Using the Cartwheel CME to Predict Off-limb Observations of CMEs for New and Upcoming UV and EUV Spectrometers

The Astrophysical Journal
Coronal mass ejections (CMEs) expel multithermal, magnetized plasma from the Sun, and when directed toward Earth, can cause extensive damage to space and ground-based electronics.

Broadening the Canonical Picture of EUV-driven Photoevaporation of Accretion Disks

The Astrophysical Journal
Photoevaporation driven by hydrogen-ionizing extreme-ultraviolet (EUV) radiation profoundly shapes the lives of diverse astrophysical objects. We construct an analytical model accounting for the finite timescales of photoheating and photoionization and ...

Quasar Spectral Energy Distributions in the Rest-frame Extreme Ultraviolet: Hubble-COS Spectra of Two Ultraluminous Quasars

The Astrophysical Journal
Using the Cosmic Origins Spectrograph (COS) on board the Hubble Space Telescope with both far-UV (FUV) and near-UV (NUV) gratings, we measure the ionizing spectra of two bright, intermediate-redshift quasars in their rest-frame extreme ultraviolet (EUV).

Detecting Stellar Coronal Mass Ejections via Coronal Dimming in the Extreme Ultraviolet

The Astrophysical Journal
Stellar flares and coronal mass ejections (CMEs) can strip planetary atmospheres, reducing the potential habitability of terrestrial planets. While flares have been observed for decades, stellar CMEs remain elusive.
