We are a research group in Computational Astrophysics within the Space Research Center (CINESPA) of the University of Costa Rica. We are working on a variety of topics including star formation, stellar evolution and neutron stars, using state-of-the art simulations. The name of our group, bë´iwä´, means "star" in the Chirripó Cabecar language (Chirripó is also the name of the tallest mountain in Costa Rica).

Research Highlights

Modeling the origin of the rotation of massive stars

Researchers from the University of Costa Rica, the University of Geneva (Switzerland) and the Yunnan Observatories (China) developed a new computational model that explains how massive stars acquire their rotation rates with accretion disks and jets, shedding light on a decades-old problem.

A septuple massive stellar system in formation

A system of seven protostars embedded in an accretion disk was spotted in the high-mass star forming region NGC 6334IN.

Feeding a baby massive star

Using the NRAO and VLA, astronomers have observed the huge flow of gas near the massive star in formation HW2 in Cepheus A. Simulations made by a member of our group have modeled the structure of the system.

The magnetic origin of protostellar jets

An international team of researchers, among them André Oliva from Beiwa-Cinespa, observed and modeled protostellar jets, confirming their magnetic origin.
