Turbulence May Promote the Birth of Massive Stars

(PhysOrg.com) -- On long, dark winter nights, the constellation of Orion the Hunter dominates the sky. Within the Hunter's sword, the Orion Nebula swaddles a cluster of newborn stars called the Trapezium. These stars are ...

ALMA demonstrates highest resolution yet

ALMA (Atacama Large Millimeter/submillimeter Array) has demonstrated the highest resolution yet with observations of an old star. The observations show that the star is surrounded by a ring-like structure of gas and that ...

Nascent gas giant planets may be lurking in dusty disk

Nurseries for new planets, protostellar disks are oblate swathes of gas and dust that rotate about newly formed stars. The Earth and the other planets in the solar system were birthed from such a disk.

A new catalog of infrared dark clouds

Infrared dark clouds (IRDCs) are dark patches of cold dust and gas seen in the sky against the bright diffuse infrared glow of warm dust in our galaxy. These IRDCs, massive and rich in molecules, are natural sites for star ...

A submillimeter survey of protostars

The formation of stars involves the complex interactions of many phenomena, including gravitational collapse, magnetic fields, turbulence, stellar feedback, and cloud rotation. The balance between these effects varies significantly ...
