R Doradus (HD 29712 or P Doradus) is a red giant variable star in the far-southern constellation Dorado, close to the border with Reticulum. Its distance from Earth is 178 light-years (55 parsecs). Having a uniform disk diameter of 57 ± 5 mas, it is thought to be the extrasolar star with the largest apparent size as viewed from Earth.

Sep 11, 2024 · For the first time, astronomers have captured detailed images that track the bubbling gas on the surface of R Doradus, a red giant located about 180 light-years away in the constellation Dorado. Let’s unravel the significance of this discovery and what it tells us about the life cycles of stars.

Sep 11, 2024 · For the first time, astronomers have captured images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained with the Atacama Large Millimeter/submillimeter Array (ALMA), in July and August 2023.

Sep 12, 2024 · New observations show the bubbling surface of the red giant star R Doradus, a feat previously only achievable with the Sun.

Sep 21, 2024 · In an unprecedented development, astronomers have managed to capture detailed images of a star outside of our solar system, including gas bubbling on its surface. These images, revealing giant hot gas bubbles larger than our …

Sep 11, 2024 · Astronomers were able to capture detailed observations of massive gas bubbles moving on the surface of a star, named R. Doradus, located 180 light-years away.

Mar 11, 1997 · R Doradus is an inconspicuous star at visible wavelength but is one of the brightest in the sky in the infrared. This led Robert Wing (Ohio State University) to predict in 1971 that R Doradus should have a large angular size.

Sep 11, 2024 · R Doradus is a red giant star, with a diameter roughly 350 times that of the Sun, located about 180 light-years away from Earth in the constellation Dorado. Its large size and proximity to...

Jul 7, 2024 · R Doradus may not be the most famous star in our night sky, but it certainly deserves our attention. As the star with the largest apparent size as seen from Earth, it offers a unique window into the life cycles of giant stars.

R Doradus is located in the far-southern constellation Dorado, about 178 light-years (or 55 parsecs) away from Earth. While R Doradus is incredibly large, it’s not as hot as some other stars. Its surface temperature is about half that of the Sun.
