Extreme Debris Disks: Insights into Violent Collisions in Planet Formation and Destruction

Kate Y. L. Su, Attila Moor, Agnes Kospal +7

Debris disks are dusty structures around mature stars, primarily identified by infrared excesses in the stellar spectra. A subset, known as extreme debris disks (EDDs), exhibits st…

Resolving the terrestrial planet-forming region of HD 172555 with ALMA: I. Post-impact dust distribution

Zoe Roumeliotis, Luca Matrà, Grant M. Kennedy +5

Giant impacts between planetary embryos are a natural step in the terrestrial planet formation process and are expected to create disks of warm debris in the terrestrial regions of…

RZ Piscium Hosts a Compact and Highly Perturbed Debris Disk

Kate Y. L. Su, Grant M. Kennedy, George H. Rieke +6

RZ Piscium (RZ Psc) is well-known in the variable star field because of its numerous, irregular optical dips in the past five decades, but the nature of the system is heavily debat…

HD 145263: Spectral Observations of Silica Debris Disk Formation via Extreme Space Weathering?

C. M. Lisse, H. Y. A. Meng, M. L. Sitko +9

We report here time domain infrared spectroscopy and optical photometry of the HD145263 silica-rich circumstellar disk system taken from 2003 through 2014. We find an F4V host star…

Extreme Debris Disk Variability -- Exploring the Diverse Outcomes of Large Asteroid Impacts During the Era of Terrestrial Planet Formation

Kate Y. L. Su, Alan P. Jackson, Andras Gaspar +14

The most dramatic phases of terrestrial planet formation are thought to be oligarchic and chaotic growth, on timescales of up to 100-200 Myr, when violent impacts occur between lar…

The Taurus Boundary of Stellar/Substellar (TBOSS) Survey II. Disk Masses from ALMA Continuum Observations

K. Ward-Duong, J. Patience, J. Bulger +9

We report 885m ALMA continuum flux densities for 24 Taurus members spanning the stellar/substellar boundary, with spectral types from M4 to M7.75. Of the 24 systems, 22 are dete…
