Un exoplaneta gigante y gaseoso, con la misma densidad de un marshmallow, fue descubierto orbitando una fría estrella enana roja, gracias a un conjunto de dispositivos científicos que incluyen al instrumento de velocidad radial NEID, financiado por NASA, que se encuentra instalado en el Telescopio WIYN de 3,5 metros, ubicado en el Observatorio Nacional Kitt, en Arizona, Estados Unidos, y que es uno de los Programas de NOIRLab de NSF y AURA. Es el planeta gigante gaseoso más esponjoso descubierto alrededor de este tipo de estrella.

October 20, 2022 sarah JonasResearch Results

A gas giant exoplanet with the density of a marshmallow has been detected in orbit around a cool red dwarf star by a suite of instruments, including the NASA-funded NEID radial-velocity instrument on the WIYN 3.5-meter Telescope at Kitt Peak National Observatory, a Program of NSF’s NOIRLab. The planet, named TOI-3757 b, is the fluffiest gas giant planet ever discovered around this type of star.
