A research team led by the recipient of a U.S. National Science Foundation Faculty Early Career Development grant used computer simulations to determine that white dwarf stars have greater potential to host habitable planets than previously realized. The team concluded that many more stars in the Milky Way galaxy might be home to planets that could support life.

There are approximately 10 billion white dwarf stars in the Milky Way. Because such stars are colder than others, scientists have thought they likely would not support habitable exoplanets. Led by Aomawa Shields, a University of California, Irvine professor of physics and astronomy, researchers used a supercomputer provided by the NSF National Center for Atmospheric Research in Boulder, Colorado, to simulate conditions on a theoretical rocky planet orbiting a white dwarf. Using data from real exoplanets orbiting the non-white dwarf star Kepler-62, the researchers found that their simulated rocky planet could have liquid water if it closely orbited a white dwarf and had certain rotational characteristics. Their findings were published in The Astrophysical Journal.

“Not much consideration has been given to these stars’ ability to host habitable exoplanets,” says Shields. “Our computer simulations suggest that if rocky planets exist in their orbits, these planets could have more habitable real estate on their surfaces than previously thought.”

The U.S. National Science Foundation today launched a 24/7 crisis intervention helpline for members of the NSF research community who have experienced sexual assault, sexual harassment, or stalking.

The NSF Safer Science Helpline is an anonymous and secure helpline available to NSF awardees, grantees, scientists, contractors and those affiliated with supporting the mission of NSF, including all those supporting NSF’s mission throughout Antarctica and the Arctic.

“NSF is committed to ensuring a culture free from sexual assault, sexual harassment and stalking,” said Renée V. Ferranti, special assistant to the director for NSF Sexual Assault and Harassment Prevention and Response Program Office (NSF SAHPR). “The NSF Safer Science Helpline will give members of the NSF research community a safe way to access support and resources and help foster an environment free from sexual violence.”

Helpline support specialists provide live, confidential, one-on-one crisis intervention and emotional support, as well as information for reporting channels and helping connect victims of sexual harm to additional support resources.

Victims and survivors can access resources through phone, online chat and SMS text support mechanisms. All services are anonymous and secure, providing NSF community members with the help they need, anytime, anywhere. Services are trauma-informed and survivor-centered, aligning with NSF’s goals of ensuring confidentiality, safety and comprehensive care for victims and survivors.

Individuals can access the NSF Safer Science Helpline in the following ways:
