NOAO Staff on team receiving the 2015 Breakthrough Prize in Fundamental Physics

The prize, for the unexpected discovery that the expansion of the universe is accelerating, rather than slowing as had been long assumed, is a shared honor with Saul Perlmutter, Brian Schmidt, and Adam Riess leading a collaboration of 51 total prize recipients splitting $3 million. Significant work on this project was done at the CTIO Blanco 4-meter telescope by current NOAO staff members Chris Smith and Tom Matheson, and former NOAO employees Bob Schommer, Nick Suntzeff, Mark Phillips, and Alejandro Clochiatti along with various other current and former AURA employees.

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.
