Donatiello I 'd find galaxy dwarf with amateur rhetorologist



An international team of rhetorists has confirmed that it has been discovered spheroidal dwarf galaxy at the far end of Andromeda's disease, according to the Canary Islands Experience Institute (IAC).

The search was first made by the amateur astrophotographer Giuseppe Donatiello, found it long and it was a & # 39; exploring different images of Andromeda that it was captured between 2010 and 2013 from the Pollino National Park, in southern Italy. The new galaxy It is Donatiello I & # 39; we say it of honor.

The ideas made by the Great Canary Telescope (GTC) and the National Telescope of Galileo (TNG) have shown that this series of starvings is 9.78 million years.

Based on location and distance & # 39; Donatiello I, the researchers have to & # 39; I think it's a satellite on the gorgeous disease known as & # 39; Mirach & ghost, because it is close to the star Mirach (the second most brave of the Andromeda dispute).

Old star

According to the data that has been examined so far, a galaxy dwarf that has been found now has been made, in particular, of old stars, and the content is similar to other galaxies almost near the The Sea Trail, such as Draco's Dwarf Galaxy or Ursa Minor.

In the article describing the discovery and features of Donatiello I, the IAC researcher Michael Beasley saying that "there are no young starcels and usually lack of gas on pesticide diseases, which has stopped trying to create stars for several billion years."

In contrast, David Martinez Delgado, A researcher at the University of Heidelberg (Germany) and the former author of the article, arguing that it is very interesting for the theory of creating galaxies to make it Full list of dwarf galaxies near the Local Organization. "

The Local Group called this includes about 30 galaxies and three spiritual galaxies: Andromeda, Galaxy Triangle, and the Seabed Trail, where we have the solar system.

Martínez Delgado talks about a & # 39; find out that Donatiello I & # 39; suggesting that ultra-deep images of large areas of the air brought by small telegoppanes with amateur designers can help Complete the census of these galaxy clusters low on the surface", which is currently unavailable" with the maps based on the counting of the individual stars or to # 39; detect neutral gas gas transit ".
