Baby stars hatch stellar eggs near galaxy center
2021/4/9
Astronomers have found stellar eggs containing baby stars around the center of the Milky Way galaxy. To make the discovery, the scientists used NSF's Atacama Large Millimeter/submillimeter Array (ALMA...
Astronomers find a golden glow from a distant stellar collision（图）
Astronomers golden glow distant stellar collision
2019/11/15
An NSF-supported team of astronomers found new evidence of the occurrence of a kilonova -- a cosmic explosion that creates massive amounts of gold and platinum -- that went unnoticed during initial ob...
New Stellar Streams Confirm ‘Melting Pot’History of the Galaxy（图）
New Stellar Streams Melting Pot History of the Galaxy
2018/1/31
Where do the stars in our Galaxy come from? All the stars we see in the night-time sky belong to our Milky Way galaxy, and while most stars were likely born here, in the Milky Way, many appear to have...
Protostar Blazes Bright,Reshaping Its Stellar Nursery
Protostar Blazes Bright Reshaping Stellar Nursery
2017/3/30
A massive protostar, deeply nestled in its dust-filled stellar nursery, recently roared to life, shining nearly 100 times brighter than before. This outburst, apparently triggered by an avalanche...
Dust grains could be remnants of stellar explosions billions of years ago
Dust grains remnants stellar explosions billions
2016/3/21
Microscopic dust particles have been found in meteoritic material on Earth, particles that were likely formed in stellar explosions that occurred long before the creation of our star, the sun.Whether ...

Microscopic dust particles have been found in meteoritic material on Earth, particles that were likely formed in stellar explosions that occurred long before the creation of our star, the sun.Whether ...
That is just what happens in an unnamed binary star system nearly 10,000 light years from Earth. The newly discovered system, known only by its astronomical catalog number TYC 2505-672-1, sets a new r...

When stellar center gasification substance thermal expansion force is greater than stellar center minimum pressure, from stellar center, pressure minimal two symmetrical directions, jet out two shares...
Study of Andromeda's stellar disk indicates more violent history than Milky Way（图）
Andromeda's stellar more violent history Milky Way
2015/1/20
A detailed study of the motions of different stellar populations in the disk of the Andromeda galaxy has found striking differences from our own Milky Way, suggesting a more violent history of mergers...
HST Pa Survey of the Galactic Center – Searching the missing young stellar populations within the Galactic Center
star formation process
2014/12/20
We present preliminary results of our \hst Pa$\alpha$ survey of the Galactic Center (\gc), which maps the central 0.65$\times$0.25 degrees around Sgr A*. This survey provides us with a more complete i...
An optical study of the faint end of the stellar luminosity function
Stars Photometric functions Multicolor metering Height of fuzzy Projection Molecular cloud
2014/12/9
We implement a new method by which to study the faint end of the field star luminosity function. The method relies on deep, multicolor photometry of fields projected against highly obscured, nearby mo...
Emission line diagnostics of magnetospheric accretion in young stellar objects
Line emission Stars Accretion Star formation Formation of the accretion flow Stars Magnetic layer
2014/12/9
This thesis seeks to explain the nature of line emission observed in young stellar objects, and to use the lines as diagnostics of the accretion process that is central to star formation. We maintain ...
Multiwavelength study of parsec scale outflows associated with low mass young stellar objects
Arrow flow Low quality of the original star formation Optical observation star
2014/12/9
A multi-wavelength, multi-telescope observational study of recently discovered parsec-scale Herbig-Haro flows associated with the earliest stages of low mass protostellar formation is presented. Impro...
NOAO/Gemini: Sakurai's Object: Stellar evolution in real time
NOAO/Gemini Sakurai's Object Stellar evolution real time
2014/4/16
Stellar lifetimes are measured in billions of years, so changes in their appearance rarely take place on a human timescale. Thus an opportunity to observe a star passing from one stage of life to anot...
Astronomers know that while large stars can end their lives as violently cataclysmic supernovae, smaller stars end up as planetary nebulae--colorful, glowing clouds of dust and gas. In recent decades,...
