Increasing planet-stirring efficiency of debris disks by "projectile stirring" and "resonant stirring"
Tyson Costa, Tim D. Pearce, Alexander V. Krivov
Extrasolar debris disks are detected by observing dust, which is thought to be released during planetesimal collisions. This implies that planetesimals are dynamically excited ("st…
The effect of sculpting planets on the steepness of debris-disc inner edges
Tim D. Pearce, Alexander V. Krivov, Antranik A. Sefilian +6
Debris discs are our best means to probe the outer regions of planetary systems. Many studies assume that planets lie at the inner edges of debris discs, akin to Neptune and the Ku…
Self-gravity of debris discs can strongly change the outcomes of interactions with inclined planets
Pedro P. Poblete, Torsten Löhne, Tim D. Pearce +1
Drastic changes in protoplanets' orbits could occur in the early stages of planetary systems through interactions with other planets and their surrounding protoplanetary or debris…
How much large dust could be present in hot exozodiacal dust systems?
T. A. Stuber, F. Kirchschlager, T. D. Pearce +3
An infrared excess over the stellar photospheric emission of main-sequence stars has been found in interferometric surveys, commonly attributed to the presence of hot exozodiacal d…
The clumpy structure of Eridani's debris disc revisited by ALMA
Mark Booth, Tim D. Pearce, Alexander V. Krivov +8
Eridani is the closest star to our Sun known to host a debris disc. Prior observations in the (sub-)millimetre regime have potentially detected clumpy structure in the disc and…
Astrometric Accelerations as Dynamical Beacons: A Giant Planet Imaged Inside the Debris Disk of the Young Star AF Lep
Kyle Franson, Brendan P. Bowler, Yifan Zhou +13
We present the direct imaging discovery of a giant planet orbiting the young star AF Lep, a 1.2 member of the 24 3 Myr Pic moving group. AF Lep was observed a…
