Herbig-Haro (HH) 211
(Preview)
Astronomers find jets everywhere when they look into space. Small jets spout from newborn stars, while huge jets blast out of the centres of galaxies. Yet despite their commonness, the processes that drive them remain shrouded in mystery. Even relatively nearby stellar jets hide their origins be...

Rho Cassiopeiae
(Preview)
One of the most distant stars thats visible to the unaided eye is also one of the most dramatic. A few years ago, astronomers watched as the star blasted hot gas into space -- enough material to make up all the planets and moons in our solar system 20 times over. The star is called Rho Cassiopeia -- Rho Cas f...

Title: HR 710 (HD 15144): An ultra-Sr-rich, magnetic Ap star with a close companion Authors: C. R. Cowley S. Hubrig The magnetic, chemically peculiar A-star HR 710 (HD 15144, ADS 1849A, AB Cet) has a close companion in a nearly circular orbit. Its 3-day period is unusually short for such stars. The sy...

(Preview)
A developing star wrapped in a black cocoon of dust is seen sprouting giant jets in a new image from NASA's Spitzer Space Telescope. The stellar portrait, seen in infrared light, offers the first glimpse at a very early stage in the life of an embryonic sun-like star -- a time when the star's natal envel...

TVLM513-46546
(Preview)
A dwarf star with a surprisingly magnetic personality and a huge hot spot covering half its surface area is showing astronomers that life as a cool dwarf is not necessarily as simple and quiet as they once assumed. Simultaneous observations made by four of the most powerful Earth- and space-based te...
