GJ 367b: A dense ultra-short period sub-Earth planet transiting a nearby red dwarf star

Publications

Authors:

Publicated:
2 December 2021.

Authors:
K. W. F. Lam, Sz. Csizmadia, N. Astudillo-Defru et al.

Summary:
Ultra-short-period (USP) exoplanets have orbital periods shorter than one day. Precise masses and radii of USPs could provide constraints on their unknown formation and evolution processes. We report the detection and characterization of the USP planet GJ 367b using high precision photometry and radial velocity observations.

Oben sieht man, wie das licht eines Sterns durch ein stilisiertes Prisma in seine Farben aufgebrochen wird. Daneben das ungestörte Sternenlichtspektrum in Diagrammform. Unten fällt das Sternenlicht erst durch die Atmosphäre eines Sterns, bevor es durch das Prisma aufgefächert wird. Einige Linien in dem Farbspektrum sind schwarz. Danabene das auf diese Art beeinflusste Sternenpektrum in Diagrammform, mit gut sichtbaren Absorptionslineien.
