Astronomer Ryan Lau of NSF’s NOIRLab, principal investigator of the Webb Early Release Science program that observed the star, shares his thoughts on the … Types of Stars. NASA’s Solar Dynamics Observatory captured this image of our 4.6-billion-year-old Sun, a main sequence star. Scientists expect it will remain one for another 5 billion years before becoming a red giant. Credit: NASA's Scientific Visualization Studio/SDO.

Some types change into others very quickly, while others stay relatively unchanged over trillions of years. See more A normal star forms from a clump of dust and gas in a stellar nursery. Over hundreds of thousands of years, the clump gains mass, starts to spin, and heats up. When the clump's … See more After a red giant has shed all its atmosphere, only the core remains. Scientists call this kind of stellar remnant a white dwarf. A white dwarf is usually Earth-size but … See more When a main sequence star less than eight times the Sun’s mass runs out of hydrogen in its core, it starts to collapse because the energy produced by fusion is the only force fighting gravity’s tendency to pull matter together. … See more

WebSubdwarf B (sdB) stars are extreme horizontal branch stars with high temperature and gravity. The explanation for the formation of sdBs is widely unknown. A common theory is that they are the result of interactions in a binary system. About 30% of the sdB stars experience pulsations, and the brightness of the star varies in a cycle.
