A Substellar Companion to Pleiades HII 3441

, 2016
We find a new substellar companion to the Pleiades member star, Pleiades HII 3441, using the Subaru telescope with adaptive optics. The discovery is made as part of the high-contrast imaging survey to search for planetary-mass and substellar companions ...

Cool stars in NGC 2547 and pre main sequence lithium depletion [PDF]

, 2003
We present the results of a spectroscopic survey of X-ray selected, low-mass candidate members of the young open cluster NGC 2547. Using a combination of photometry, spectroscopic indices and radial velocities we refine our candidate list and then use ...

Mapping snow depth in open alpine terrain from stereo satellite imagery [PDF]

The Cryosphere, 2016
To date, there is no definitive approach to map snow depth in mountainous areas from spaceborne sensors. Here, we examine the potential of very-high-resolution (VHR) optical stereo satellites to this purpose. Two triplets of 0.70 m resolution images were

Evidence of radius inflation in stars approaching the slow-rotator sequence [PDF]

, 2016
Average stellar radii in open clusters can be estimated from rotation periods and projected rotational velocities under the assumption of random orientation of the spin axis. Such estimates are independent of distance, interstellar absorption, and models,
