SMA News and Events: 2011
December 1, 2011
Hot Cores in Dark Clouds
Science Update
The earliest stages in the life of a star are among the most mysterious. This is primarily because stars form inside dark clouds of material that block optical light, and because they form relatively quickly, in only hundred of thousands of years, whereas once a star starts burning its hydrogen fuel it can last for billions of years.

Water and Ammonia Factories
Science Update
Complex molecules, including many organic species, exist in a wide range of environments in the cosmos, and are especially abundant in giant molecular clouds of gas and dust where new stars form.

Dark Clouds in Space
Science Update
How do massive stars form? Stars with more than about eight times as much mass as the sun are arguably the most important actors in the universe.

SMA Event: SMA Community Day
The meeting format will consist of both scientific and technical talks with ample time for discussion and questions. The scientific program will run before lunch. In the early afternoon, a technical program will introduce the SMA to assist those thinking about or planning SMA observations. While primarily intended for the CfA community, the meeting is open to astronomers from other institutions. There is no registration fee, but if you plan to attend, we would appreciate it if you could register below so that we can determine how many people to expect.

Want to Make Planets? Better Hurry.
News Release: Universe Today article by Jon Voisey
"Currently, astronomers have two competing models for planetary formation. In one, the planets form in a single, monolithic collapse. In the second, the core forms first and then slowly accretes gas and dust. However, in both situations, the process must be complete before the radiation pressure from the star blows away the gas and dust. While this much is certain, the exact time frames have remained another matter of debate. It is expected that this amount should be somewhere in the millions of years, but low end estimates place it at only a few million, whereas upper limits have been around 10 million."

Magnetic Fields in Interstellar Clouds
Science Update
Magnetic Fields in Interstellar Clouds Thursday, March 24, 2011 Science Update - A look at CfA discoveries from recent journals Magnetic fields play an important role in the formation and evolution of stars, as they stretch around a hot medium like a rubber band and help to determine the flow of material onto or away from the star.

The Rich Chemistry Around an Evolved Star
Science Update
Over 170 molecules have been detected in space, from simple diatomic molecules like CO to complex organic molecules with over 70 atoms, like fullerene.

A Wealth of Molecules in an Extreme Galaxy
Science Update
Arp 220 is the closest galaxy to the Milly Way with an extreme luminosity, defined as being more than about 300 times that of our own galaxy. Some dramatic galaxies have values of luminosity ten times brighter still.
