Diversity of planetary systems in low-mass disks: Terrestrial-type planet formation and water delivery
(EDP Sciences, 2014-07)
Context. Several studies, observational and theoretical, suggest that planetary systems with only rocky planets are the most common in the Universe.<br />Aims. We study the diversity of planetary systems that might form ...
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 ...
Physical properties of terrestrial planets and water delivery in the habitable zone using N-body simulations with fragmentation
(EDP Sciences, 2019-11-13)
The goal of this research is to study how the fragmentation of planetary embryos can affect the physical and dynamical properties of terrestrial planets around solar-type stars. Our work focuses on the formation and evolution ...
Thermal torque effects on the migration of growing low-mass planets
(Wiley Blackwell Publishing, Inc, 2019-07)
As planets grow the exchange of angular momentum with the gaseous component ofthe protoplanetary disc produces a net torque resulting in a variation of the semi-major axis of the planet. For low-mass planets not able to ...
The intriguing nature of the high-energy gamma ray source XSS J12270-4859
(EDP Sciences, 2010-06)
The nature of the hard X-ray source XSS J12270-4859 is still unclear. It was claimed to be a possible magnetic Cataclysmic Variable of the Intermediate Polar type from its optical spectrum and a possible 860 s X-ray ...
Low-level Carbon Monoxide Line Polarization in Two Protoplanetary Disks: HD 142527 and IM Lup
(IOP Publishing, 2020-09)
Magnetic fields are expected to play an important role in accretion processes for circumstellar disks. However, measuring the magnetic field morphology is difficult, especially when given that polarimetric (sub)millimeter ...
Planet heating prevents inward migration of planetary cores
(Nature Publishing Group, 2015-04)
Planetary systems are born in the disks of gas, dust and rocky fragments that surround newly formed stars. Solid content assembles into ever-larger rocky fragments that eventually become planetary embryos. These then ...
SU Lyn: Diagnosing the Boundary Layer with UV and Hard X-Ray Data
(IOP Publishing, 2018-08)
Symbiotic stars in which the symbiotic phenomenon is powered solely by accretion, often at an average rate that is higher than in cataclysmic variable stars, provide an important opportunity to diagnose boundary layers ...
Its moderately extended low-density halo and its accretion history
(EDP Sciences, 2020-02-06)
We present results based on Dark Energy Camera Legacy Survey (DECaLS) DR8 astrometric and photometric data sets of the Milky Way globular cluster Pal 13. Because of its relatively small size and mass, there is not yet a ...
Formation imprints in the kinematics of the Milky Way globular cluster system
(IOP Publishing, 2019-07)
We report results on the kinematics of Milky Way (MW) globular clusters (GCs) based on updated space velocities for nearly the entire GC population. We found that a 3D space with the semimajor axis, the eccentricity, and ...
