Deep Search for a Scattered Light Dust Halo Around Vega with the Hubble Space Telescope

The Astronomical Journal
We present a provisory scattered-light detection of the Vega debris disk using deep Hubble Space Telescope (HST) coronagraphy (PID 16666). At only 7.7 pc, Vega is immensely important in debris disk studies both for its prominence and also because it ...

Exploring the Complex Ionization Environment of the Turbulent DM Tau Disk

The Astrophysical Journal
Ionization drives important chemical and dynamical processes within protoplanetary disks, including the formation of organics and water in the cold midplane and the transportation of material via accretion and magnetohydrodynamic flows.

Light Echoes of Time-resolved Flares and Application to Kepler Data

The Open Journal of Astrophysics
Light echoes of stellar flares provide an intriguing option for exploring protoplanetary disks in young stellar systems. Previous work on light echoes of circumstellar disks made use of delta-function flares for modeling.

A Census of the β Pic Moving Group and Other Nearby Associations with Gaia

The Astronomical Journal
I have used the third data release of the Gaia mission to improve the reliability and completeness of membership samples in the β Pic moving group (BPMG) and other nearby associations with ages of 20–50 Myr (Sco Body, Carina, Columba, χ ^1 For, Tuc-Hor ...

The First JWST View of a 30-Myr-old Protoplanetary Disk Reveals a Late-stage Carbon-rich Phase

The Astrophysical Journal Letters
We present a JWST MIRI/MRS spectrum of the inner disk of WISE J044634.16–262756.1B (hereafter J0446B), an old (∼34 Myr) M4.5 star but with hints of ongoing accretion. The spectrum is molecule-rich and dominated by hydrocarbons.
