Herbig–Haro object - Wikipedia
WitrynaThe HH stands for Herbig-Haro object. A Herbig-Haro object is formed when a jet of gas ejected by a young star collides and interacts with its parent cloud of gas and dust at several hundred kilometres per second. These highly energetic areas of space are often signposts of star formation. In the centre left of this image, there is a red ... WitrynaHH 46/47 is a complex of Herbig–Haro objects (HH objects), located around 450 parsecs (about 1,470 light-years) away in a Bok globule near the Gum nebula. Jets of … Herbig–Haro (HH) objects are bright patches of nebulosity associated with newborn stars. They are formed when narrow jets of partially ionised gas ejected by stars collide with nearby clouds of gas and dust at several hundred kilometres per second. Herbig–Haro objects are commonly found in star … Zobacz więcej The first HH object was observed in the late 19th century by Sherburne Wesley Burnham, when he observed the star T Tauri with the 36-inch (910 mm) refracting telescope at Lick Observatory and noted a small patch of … Zobacz więcej Electromagnetic emission from HH objects is caused when their associated shock waves collide with the interstellar medium, creating what … Zobacz więcej HH objects are named approximately in order of their identification; HH 1/2 being the earliest such objects to be identified. More than a thousand individual objects are now known. They are always present in star-forming H II regions, and are often found in large … Zobacz więcej HH objects associated with very young stars or very massive protostars are often hidden from view at optical wavelengths by the cloud of gas and dust from which they form. The intervening material can diminish the visual magnitude by factors of tens or even … Zobacz więcej Stars form by gravitational collapse of interstellar gas clouds. As the collapse increases the density, radiative energy loss decreases due to increased opacity. This raises the … Zobacz więcej The stars from which HH jets are emitted are all very young stars, a few tens of thousands to about a million years old. The youngest of these are still protostars in the process of collecting from their surrounding gases. Astronomers divide these stars into … Zobacz więcej HH objects have been observed in the ultraviolet spectrum. Zobacz więcej sub washpost
