Finding New Debris Discs at Sub-millimetre Wavelengths

Mark Booth, Patricia Luppe, Sebastian Marino +9

Debris discs reveal the architectures and dynamical histories of planetary systems. Sub-millimetre observations trace large dust grains within debris discs, revealing their bulk pr…

Systematic determination of dust properties for a sample of 133 spatially resolved debris discs

J. P. Marshall, S. Hengst, R. Young +6

Determination of the composition and size distribution of dust grains in debris discs is strongly dependent on constraining the underlying spatial distribution of that dust through…

Formation of Giant Planets

Masahiro Ikoma, Hiroshi Kobayashi

Gas giant planets, if present, are the most massive objects in a planetary system and play a pivotal role in shaping its overall architecture. The formation of these planets has co…

Frequencies of warm debris disks based on point source catalogs of Spitzer, WISE, and Gaia

Toshiyuki Mizuki, Munetake Momose, Masataka Aizawa +1

More than a thousand warm debris disks have been detected as infrared excess at mid-infrared wavelengths, and their frequencies have been obtained for various spectral types of sta…

A Primordial Origin for the Gas-Rich Debris Disks Around Intermediate-Mass Stars

Riouhei Nakatani, Neal J. Turner, Yasuhiro Hasegawa +4

While most debris disks consist of dust with little or no gas, a fraction has significant amounts of gas detected via emission lines of CO, ionized carbon, and/or atomic oxygen. Al…

Rapid Formation of Gas-giant Planets via Collisional Coagulation from Dust Grains to Planetary Cores. II. Dependence on Pebble Bulk Density and Disk Temperature

Hiroshi Kobayashi, Hidekazu Tanaka

Thanks to ``dust-to-planet'' simulations (DTPSs), which treat the collisional evolution directly from dust to giant-planet cores in a protoplanetary disk, we showed that giant-plan…

Understanding how planets become massive. I. Description and validation of a new toy model

Chris Ormel, Hiroshi Kobayashi

The formation of giant planets requires accumulation of ~10 Earth mass in solids; but how do protoplanets acquire their mass? There are many, often competing processes that regulat…
