JWST/MIRI Imaging of the Warm Dust Component of the Epsilon Eridani Debris Disk
Schuyler G. Wolff, András Gáspár, George Rieke +4
We present JWST/MIRI observations of the debris disk surrounding the nearby, solar analog Epsilon Eridani obtained as part of the Archetypal Debris Disk GTO program. Multi-waveleng…
The polar debris disc around 99 Herculis: A potential signpost for polar circumbinary planets
Jeremy L. Smallwood, William DeRocco, Zhizhen Qin +1
The nearby binary star system 99 Herculis (99 Her) is host to the only known polar-aligned circumbinary debris disc. We investigate the hypothesis that the narrow structure of this…
ALMA Reveals an Eccentricity Gradient in the Fomalhaut Debris Disk
Joshua B. Lovell, Elliot M. Lynch, Jay Chittidi +6
We present evidence of a negative eccentricity gradient in the debris disk of the nearby A-type main sequence star, Fomalhaut. Fitting to the high-resolution, archival ALMA 1.32 mm…
The Influence of Cold Jupiters in the Formation of Close-in planets. II. Collisional Growth of Planetesimals
Marcela Best, Antranik A. Sefilian, Carolina Charalambous +2
Exoplanet observations have shown that the occurrence and orbital architectures of close-in super-Earths and sub-Neptunes are shaped by the presence of outer gas giant planets. Thi…
Testing the Impact of Planet-stirring, Self-stirring, and Mixed-stirring on Debris Disc Architecture: A Case Study of HD 16743
Jonathan P. Marshall, Marco A. Muñoz-Gutiérrez, Antranik A. Sefilian +1
Dynamical interactions between planets and debris discs can excite the orbits of embedded planetesimals to such a degree that a collisional cascade is triggered, generating detecta…
The vertical structure of debris discs and the role of disc gravity: A primer using a simplified model
Antranik A. Sefilian, Kaitlin M. Kratter, Mark C. Wyatt +4
Debris discs provide valuable insights into the formation and evolution of exoplanetary systems. Their structures are commonly attributed to planetary perturbations, serving as pro…
Dust populations from 30 to 1000 au in the debris disk of HD 120326
C. Desgrange, J. Milli, G. Chauvin +15
Context. To date, more than a hundred debris disks have been spatially resolved. Among them, the young system HD 120326 stands out, displaying different disk substructures on both…
