The images, taken on March 22, 2023, and released Wednesday, showcase different dynamic aspects of the sun, including the movements of its magnetic field and the glow of the ultrahot solar corona ...
The star is 1.117 M sun and 1.555 R sun, or 111% the mass of and 155% the radius of the Sun. [5] With a metallicity of .09 (± 0.10) [Fe/H], Kepler-4 is more metal-rich than the Sun, a figure that is important in that metal-rich stars tend to have orbiting planets more often than metal-poor stars. Kepler-4 is also about 6.7 billion years old. [5]
The star is colder and smaller than the Sun, having a temperature of 3,457 K (3,184 °C; 5,763 °F) and a radius 45% of the Sun's, [6] and is not visible to the naked eye. [7] The star is 2.4 ± 0.6 billion years old [ 8 ] and displays moderate stellar activity , but whether it has star spots , [ 9 ] which would tend to create false signals [ a ...
The orrery was created by Fabrycky, then a postdoc at the University of California, Santa Cruz, largely due to an accident.When he created an animation of a six-planet system Kepler-11 for his work on a home computer in 2011, his son and daughter were found playing with the program.
Scientists analyzed famed astronomer Johannes Kepler’s 1607 sketches of sunspots to solve a mystery about the sun’s solar cycle that has persisted for centuries.
Both stars are smaller than the Sun; the primary, Kepler-16A, is a K-type main-sequence star and the secondary, Kepler-16B, is an M-type red dwarf. They are separated by 0.22 AU, and complete an orbit around a common center of mass every 41 days. The system is host to one known extrasolar planet in circumbinary orbit: the Saturn-sized Kepler-16b.
Kepler-444 (or KOI-3158, KIC 6278762, 2MASS J19190052+4138043, BD+41°3306) [10] is a triple star system, estimated to be 11.2 billion years old (more than 80% of the age of the universe), [12] approximately 119 light-years (36 pc) away from Earth in the constellation Lyra.
Kepler-62 is a K-type main sequence star cooler and smaller than the Sun, located roughly 980 light-years (300 parsecs) from Earth in the constellation Lyra. It resides within the field of vision of the Kepler spacecraft , the satellite that NASA 's Kepler Mission used to detect planets that may be transiting their stars.
