Effects of Hadron-Quark Phase Transitions in Hybrid Stars within the NJL Model
Autor: Ignacio Francisco Ranea-Sandoval, Milva Gabriela Orsaria, Germán Malfatti, Daniela Curin, Mauro Mariani, Gustavo Aníbal Contrera, Octavio Miguel Guilera
Publikováno v: Symmetry, Vol 11, Iss 3, p 425 (2019)
We study local and non-local Polyakov Nambu-Jona-Lasinio models and analyze their respective phase transition diagram. We construct hybrid stars using the zero temperature limit of the local and non-local versions of Nambu-Jona-Lasinio model for quar

Discontinuity g ‐modes of hybrid stars: Effect of sequential phase transitions
Autor: Maria Camila Rodríguez, Ignacio F. Ranea-Sandoval, Octavio Miguel Guilera, Germán Malfatti, Mauro Mariani
Publikováno v: Astronomische Nachrichten. 342:305-309
The detection of event GW170817 and its electromagnetic counterpart started the era of multi‐messenger astronomy with gravitational waves. The observational constraints from this event and the estimation of mass and radius of PSR J0030 + 0451 is be

Long live the disk: lifetimes of protoplanetary disks in hierarchical triple star systems and a possible explanation for HD 98800 B

The gas dissipation from a protoplanetary disk is one of the key processes affecting planet formation, and it is widely accepted that it happens on timescales of a few million years for disks around single stars. Over the last years, several protopla

A key process in planet formation is the exchange of angular momentum between a growing planet and the protoplanetary disc, which makes the planet migrate through the disc. Several works show that in general low-mass and intermediate-mass planets mig

Neutron stars are the densest objects in the Universe, with M ∼ 1.4M☉ and R ∼ 12 km, and the equation of state associated to their internal composition is still unknown. The extreme conditions to which matter is subjected inside neutron stars c

The Nature of the Radius Valley: Hints from Formation and Evolution Models
Autor: Christoph Mordasini, María Paula Ronco, Julia Venturini, Octavio Miguel Guilera, J. Haldemann
The existence of a Radius Valley in the Kepler size distribution stands as one of the most important observational constraints to understand the origin and composition of exoplanets with radii between that of Earth and Neptune. The goal of this work

Setting the Stage: Planet formation and Volatile Delivery
Autor: Octavio Miguel Guilera, María Paula Ronco, Julia Venturini
The diversity in mass and composition of planetary atmospheres stems from the different building blocks present in protoplanetary discs and from the different physical and chemical processes that these experience during the planetary assembly and evo

In about 6 Giga years our Sun will evolve into a red giant and finally end its life as a white dwarf. This stellar metamorphosis will occur to virtually all known host stars of exo-planetary systems and is therefore crucial for their final fate. It i

Thermal torque effects on the migration of growing low-mass planets

As planets grow the exchange of angular momentum with the gaseous component of the 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 open a gap in the gaseous dis
