Infant Solar System Shows Signs of
Windy Weather

NOAO astronomer Colette Salyk has led a study using ALMA that suggests that the winds around some T Tauri stars may explain their unpredictable infrared glow.

HD100546 and Circumstellar Disk with Extrasolar Planet

In a recently published paper, NOAO astronomer Joan Najita was part of a team that has shown evidence for a planet forming in the disk around a young star. The results provide perhaps the first evidence that planets are surrounded by a circumplanetary disk at birth. This figure is an artist’s conception of the young massive star HD100546 and its surrounding disk. A planet forming in the disk has cleared the disk within 13 AU of the star, a distance comparable to that of Saturn from the sun. As gas and dust flows from the circumstellar disk to the planet, this material surrounds the planet as a circumplanetary disk (inset). These rotating disks are believed to be the birthplaces of planetary moons, such as the Galilean moons that orbit Jupiter.

Half of all Exoplanet Host Stars are Binaries

Imagine living on an exoplanet with two suns. One, you orbit and the other is a very bright, nearby neighbor looming large in your sky. With this “second sun” in the sky, nightfall might be a rare event, perhaps only coming seasonally to your planet. A new study suggests that this could be far more common than we realized.

NOAO Newsletter

The September 2014 NOAO Newsletter is online and ready to download. This issue includes information pertaining to the 2015A Call for Proposals, which are due September 25, 2014.

On the Cover
The cover shows an 8 × 9 arcminutes image of a portion of the Milky Way galactic bulge, obtained as part of the Blanco DECam Bulge Survey (BDBS) using the Dark Energy Camera (DECam) on the CTIO Blanco 4-m telescope. In this image, red, green, and blue (RGB) pixels correspond to DECam’s Y, z and i filters, respectively.

The inset image shows the 2 × 3 array of monitors at the “observer2” workstation in the Blanco control room. The six chips shown here represent only 10% of the camera’s field of view.

Dr. Arlo Landolt: 55 years of Observing at the National Observatories

Dr. Arlo Landolt, Ball Professor Emeritus of physics and astronomy at Louisiana State University, was recently celebrated for his 55 years of observing at Kitt Peak National Observatory (KPNO), almost all devoted to service to the astronomical community. In the summer of 1959, Dr. Landolt was the first guest observer at KPNO when the only telescope on the mountain was the 16-inch site survey telescope.
