Gemini South Confirms Long-Suspected Link Between the Composition of Exoplanets and Their Host Stars

Gemini South confirms long-suspected link between the composition of exoplanets and their host stars

Astronomers have discovered that a giant planet, WASP-189b, echoes the composition of its host star, providing the first direct evidence of a foundational concept in astrobiology. This discovery was achieved through the first-ever simultaneous measurement of gaseous magnesium and silicon in a planet's atmosphere. The team used the Gemini South telescope, one half of the International Gemini Observatory. The findings are published in the journal …

Discovering WASP-189b: Superhot Jupiter Reveals Star's Chemical Makeup, Astronomers Find

Astronomers utilizing the Immersion Grating Infrared Spectrometer (IGRINS) at the International Gemini Observatory’s Gemini South Telescope have made groundbreaking discoveries regarding WASP-189b’s atmospheric composition. Their findings indicate that the planet’s elemental composition closely aligns with that of its host star, offering compelling evidence that the planet inherits its chemical makeup from the protoplanetary disk from [...] The …

El fin de una larga suposición: Gemini Sur confirma relación entre la composición de exoplanetas y sus estrellas

Astrónomos descubrieron que el planeta gigante WASP-189b refleja la composición química de su estrella anfitriona, aportando la primera prueba directa de un concepto fundamental en astrobiología. Este descubrimiento fue posible gracias a la primera medición simultánea de magnesio y silicio en estado gaseoso en la atmósfera de un planeta. El equipo utilizó el telescopio Gemini Sur, una mitad del Observatorio Internacional Gemini, financiado en par

Ultra-Hot Jupiter WASP-189b Mirrors Its Star’s Chemistry, Astronomers Find

Using the Immersion Grating Infrared Spectrometer (IGRINS) on the Gemini South telescope at the International Gemini Observatory, astronomers have directly measured the atmospheric composition of WASP-189b and found it echoes the elemental makeup of its host star.

Gemini South Confirms Long-Suspected Link Between the Composition of Exoplanets and Their Host Stars - New observations provide the first direct evidence that exoplanets inherit rocky-element ratios from their host stars

Astronomers discovered that a giant planet, WASP-189b, echoes the composition of its host star, providing the first direct evidence of a foundational concept in astrobiology. This discovery was achieved through the first-ever simultaneous measurement of gaseous magnesium and silicon in a planet’s atmosphere. The team used the Gemini South telescope, one half of the International Gemini Observatory, partly funded by the U.S. National Science Found
