Espectro de transmisión WASP-107 B de exoplaneta de gas cálido (NIRSPEC)

Espectro de transmisión WASP-107 B de exoplaneta de gas cálido (NIRSPEC)

Este espectro de transmisión, capturado utilizando el NIRSPEC de Webb (espectrógrafo de infrarrojo cercano), muestra las cantidades de diferentes longitudes de onda (colores) de la luz de estrella de infrarrojo cercano bloqueado por la atmósfera del exoplaneta-gigante de gas wasp-107 b .

El espectro se realizó al observar el sistema planet-star durante aproximadamente 8.5 horas, durante, y después del transit. la cara de la estrella.  

Al comparar el brillo de la luz filtrada a través de la atmósfera del planeta (luz transmitida) con la luz de la estrella sin filtro, es posible calcular la cantidad de cada longitud de onda que está bloqueada por la atmósfera. Dado que cada molécula absorbe una combinación única de longitudes de onda, el espectro de transmisión se puede usar para restringir la abundancia de varios gases.

Este espectro muestra evidencia clara de agua (h 2 o), diioxido de carbono (co ), monóxido de carbono (co), metano (CH 4 ), y SECHUD y SECHIDE DOMHIDE DOMED, ​​Monóxido de carbono (Co), metano (CH 4 ), y SECHUD y SECHIDE DOM DO (SO 2 ) en la atmósfera del planeta, lo que permite a los investigadores estimar la temperatura interior y la masa del núcleo.

About The Object
Object Name A name or catalog number that astronomers use to identify an astronomical object.
Object Description The type of astronomical object.
R.A. Position Right ascension – analogous to longitude – is one component of an object's position.
Dec. Position Declination – analogous to latitude – is one component of an object's position.
Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
Distance The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
Dimensions The physical size of the object or the apparent angle it subtends on the sky.
