Mapping Gravitational Bends in Remote Star Systems
22800 light-years away, a Saturn-mass world moves around a small sun. This planet orbits an M-dwarf which is cooler than the sun. Astronomers used gravitational microlensing to find this system. This method tracks how gravity warps the path of light from background stars.
Monitoring Stellar Fluctuations
Study the light curve models to determine the mass of the celestial body. Researchers estimated the star possesses 0.54 solar masses.
Secrets of the Galactic Bulge
The Korea Microlensing Telescope Network operates 3 identical 1.6-meter telescopes in Chile, South Africa, and Australia. These machines watch the sky. The Nancy Grace Roman Space Telescope will launch in 2027 to find more planets. Additional information can be found in The Astrophysical Journal and through the NASA Exoplanet Archive. Every year the list of known worlds grows longer.
The Deadly Radiation of Small Star Systems
M-dwarf systems present a challenge for the existence of liquid water on nearby planets. Frequent flares from these small stars could destroy the chance for biological growth. A study from the University of Washington suggests that high energy particles erode planetary shields. Observations of Proxima Centauri by the Hubble Space Telescope show that these flares are quite common. Scientists argue about whether these Saturn-sized worlds can hold onto gas. Data from the KMT-2016BLG-1337L event provides a new case for study.
Catalog of the Star System
The star in this system contains 0.54 solar mass. The planet holds a mass similar to the planet Saturn. The system sits at a distance of 7000 parsecs from our own planet.
