The dust-rich, gas-depleted protosolar disk as the birthplace of chondrules
Sota Arakawa, Hidekazu Tanaka, Toshihiko Kadono +3
Chondrules are the primary components of primitive meteorites known as chondrites, and understanding their formation and accumulation is essential for elucidating the history of pl…
A Trio of Giant Planets Orbiting Evolved Star HD 184010
Huan-Yu Teng, Bun'ei Sato, Takuya Takarada +11
We report the discovery of a triple-giant-planet system around an evolved star HD 184010 (HR 7421, HIP 96016). This discovery is based on observations from Okayama Planet Search Pr…
Planet-planet scattering in presence of a companion star
Francesco Marzari, Makiko Nagasawa, Krzyszof Goździewski
Planet Planet scattering is a leading dynamical mechanism invoked to explain the present orbital distribution of exoplanets. Many stars belong to binary systems, therefore it is im…
Secular evolution of close in planets: the effects of general relativity
Francesco Marzari, Makiko Nagasawa
Pairs of planets in a system may end up close to their host star on eccentric orbits as a consequence of planet planet scattering, Kozai or secular migration. In this scenario, gen…
The influence of general-relativity effects, dynamical tides and collisions on planet-planet scattering close to the star
F. Marzari, M. Nagasawa
Planet--Planet scattering is an efficient and robust dynamical mechanism for producing eccentric exoplanets. Coupled to tidal interactions with the central star, it can also explai…
Shock-Generating Planetesimals Perturbed by a Giant Planet in a Gas Disk
M. Nagasawa, K. K. Tanaka, H. Tanaka +3
We examined the excitations of planetesimals caused by the resonances of a giant planet in a protoplanetary gas disk. The highly excited planetesimals generate bow shocks, the mech…
