Shadows cast on the transition disk of HD 135344B
(EDP Sciences, 2016)
Context. The protoplanetary disk around the F-type star HD 135344B (SAO 206462) is in a transition stage and shows many intriguing structures both in scattered light and thermal (sub-) millimeter emission which are possibly ...
The edge of the Kuiper belt: the Planet X scenario
(Elsevier, 2004-12)
Our goal is to determine whether or not the observed sudden termination of the Edgeworth–Kuiper belt can be the result of perturbations from a hypothetical planet. We investigate the effects that such an object would produce ...
Gap, shadows, spirals, and streamers: SPHERE observations of binary-disk interactions in GG Tauri A
(EDP Science, 2020)
Context. A large portion of stars is found to be part of binary or higher-order multiple systems. The ubiquity of planets found around single stars raises the question of whether and how planets in binary systems form. ...
Evolutionary stages and disk properties of young stellar objects in the Perseus cloud
(NATL ASTRONOMICAL OBSERVATORIES, CHIN ACAD SCIENCES, 2015)
We investigated the evolutionary stages and disk properties of 211 young stellar objects (YSOs) across the Perseus cloud by modeling their broadband optical to mid-infrared (IR) spectral energy distribution (SED). Our ...
Multiwavelength optical properties of compact dust aggregates in protoplanetary disks
(EDP SCIENCES, 2016)
Context. In protoplanetary disks micron-size dust grains coagulate to form larger structures with complex shapes and compositions. The coagulation process changes the absorption and scattering properties of particles in ...
Planetary formation and water delivery in the habitable zone around solar-type stars in different dynamical environments
(EDP Sciences, 2018-01)
Context. Observational and theoretical studies suggest that there are many and various planetary systems in the Universe. Aims. We study the formation and water delivery of planets in the habitable zone (HZ) around solar-type ...
Disks around T Tauri stars with sphere (DARTTS-S) II. Twenty- one new polarimetric images of young stellar disks
(EDP Sciences, 2020)
Context. Near-IR polarimetric images of protoplanetary disks enable us to characterize substructures that might be due to the interaction with (forming) planets. The available census is strongly biased toward massive disks ...
Estudo da evolução dinâmica do sistema planetário HR8799 via simulações hidrodinâmicas
(Universidade Estadual Paulista (Unesp), 2021-05-27)
Entre mais de 3300 sistemas planetários conhecidos, o sistema HR8799 é um dos mais interessantes sistemas de planetas gigantes pois, nele contém pelo menos quatro planetas gigantes gasosos, com massas superiores à de ...
Azimuthal asymmetries in the debris disk around HD61005 A massive collision of planetesimals?
(EDP Sciences, 2016)
Context. Debris disks off er valuable insights into the latest stages of circumstellar disk evolution, and can possibly help us to trace the outcomes of planetary formation processes. In the age range 10 to 100 Myr, most ...
