Building Giant-Planet Cores at a Planet Trap
Context. A well-known bottleneck for the core-accretion model of giant-planet formation is the loss of the cores into the star by Type-I migration, due to the tidal interactions with the gas disk. It has been shown that a steep surface-density gradient in the disk, such as the one expected at the boundary between an active and a dead zone, acts as a planet trap and prevents isolated cores from ...
متن کاملGiant Planet with a stratosphere ?
We have carried out a search for the 2.14 μm spectroscopic signature of the close orbiting extrasolar giant planet, HD 179949b. High cadence time series spectra were obtained with the CRIRES spectrograph at VLT1 on two closely separated nights. Deconvolution yielded spectroscopic profiles with mean S/N ratios of several thousand, enabling the near infrared contrast ratios predicted for the HD 1...
متن کاملGiant Planet Atmospheres and Spectra
Direct measurements of the spectra of extrasolar giant planets are the keys to determining their physical and chemical nature. The goal of theory is to provide the tools and context with which such data are understood. It is only by putting spectral observations through the sieve of theory that the promise of exoplanet research can be realized. With the new Spitzer and HST data of transiting “h...
متن کاملGiant Planet Migration through the Action of Disk Torques and Planet-planet Scattering
This paper presents a parametric study of giant planet migration through the combined action of disk torques and planet-planet scattering. The torques exerted on planets during Type II migration in circumstellar disks readily decrease the semi-major axes a, whereas scattering between planets increases the orbital eccentricities ǫ. This paper presents a parametric exploration of the possible par...
متن کاملMigration and giant planet formation
X iv :a st ro -p h/ 04 03 57 4v 1 2 4 M ar 2 00 4 We extend the core-accretion model of giant gaseous planets by Pollack et al. ([1996]) to include migration, disc evolution and gap formation. Starting with a core of a fraction of an Earth’s mass located at 8 AU, we end our simulation with the onset of runaway gas accretion when the planet is at 5.5 AU 1 Myr later. This timescale is about a fac...
