Do the majority of stars form as gravitationally unbound?
Context. Some of the youngest stars (age less than or similar to 10 Myr) are clustered, while many others are observed scattered throughout star forming regions or in complete isolation. It has been intensively debated whether such scattered or isolated st ...
2022Modeling the Ga/As binary system across temperatures and compositions from first principles
Michele Ceriotti, Giulio Imbalzano
Materials composed of elements from the third and fifth columns of the periodic table display a very rich behavior, with the phase diagram usually containing a metallic liquid phase and a polar semiconducting solid. As a consequence, it is very hard to ach ...
AMER PHYSICAL SOC2021Spectroscopic Orbits Of Three Dwarf Barium Stars
Barium stars are thought to result from binary evolution in systems wide enough to allow the more massive component to reach the asymptotic giant branch and eventually become a CO white dwarf. While Ba stars were initially known only among giant or subgian ...
OBSERVATORY2020Phases of granular segregation in a binary mixture
Pedro Miguel Nunes Pereira de Almeida Reis
We present results from an extensive experimental investigation into granular segregation of a shallow binary mixture in which particles are driven by frictional interactions with the surface of a vibrating horizontal tray. Three distinct phases of the mix ...
