REVISED MASSES AND DENSITIES OF THE PLANETS AROUND KEPLER-10W. MO Keck Observatory.

Weiss, Lauren M Rogers, Leslie A Isaacson, Howard T Agol, Eric Marcy, Geoffrey W Jason Rowe Kipping, David Fulton, Benjamin J Lissauer, Jack J Howard, Andrew W ...

Published in The Astrophysical Journal

Determining which small exoplanets have stony-iron compositions is necessary for quantifying the occurrence of such planets and for understanding the physics of planet formation. Kepler-10 hosts the stony-iron world Kepler-10b, and also contains what has been reported to be the largest solid silicate-ice planet, Kepler-10c. Using 220 radial velocit...

CAMS confirmation of previously reported meteor showers

Peter Jenniskens Nénon, Q Gural, P S Albers, J Haberman, B Johnson, B Holman, D Morales, R Grigsby, B J Samuels, D ...

Published in Icarus

Leading up to the 2015 IAU General Assembly, the International Astronomical Union s Working List of Meteor Showers included 486 unconfirmed showers, showers that are not certain to exist. If confirmed, each shower would provide a record of past comet or asteroid activity. Now, we report that 41 of these are detected in the Cameras for Allsky Meteor...

CAMS newly detected meteor showers and the sporadic background

Peter Jenniskens Nénon, Q Gural, P S Albers, J Haberman, B Johnson, B Morales, R Grigsby, B J Samuels, D Johannink, C ...

Published in Icarus

The Cameras for Allsky Meteor Surveillance (CAMS) video-based meteoroid orbit survey adds 60 newly identified showers to the IAU Working List of Meteor Showers (numbers 427, 445–446, 506–507, and part of 643–750). 28 of these are also detected in the independent SonotaCo survey. In total, 230 meteor showers and shower components are identified in C...

Reflectance spectroscopy (0.35–8μm) of ammonium-bearing minerals and qualitative comparison to Ceres-like asteroids

Berg, Breanne L Cloutis, Edward A Beck, Pierre Vernazza, Pierre Janice Bishop Takir, Driss Reddy, Vishnu Applin, Daniel Mann, Paul

Published in Icarus

Ammonium-bearing minerals have been suggested to be present on Mars, Ceres, and various asteroids and comets. We undertook a systematic study of the spectral reflectance properties of ammonium-bearing minerals and compounds that have possible planetary relevance (ie, ammonium carbonates, chlorides, nitrates, oxalates, phosphates, silicates, and sul...

Present-day aeolian activity in Herschel Crater, Mars

Cardinale, Marco Silvestro, Simone Vaz, David A Tim Michaels Bourke, Mary C Komatsu, Goro Marinangeli, Lucia

Published in Icarus

We estimate an average dune migration of 0.8 m and a minimum ripple migration of 1.1 m in a time span of 3.7 Earth-years. These dunes and ripples are mainly shaped by prevailing winds coming from the north, however we also report the presence of secondary winds which elongate the barchans horns. Such a complex wind scenario is likely caused by the...

Identifying False Alarms in the Kepler Planet Candidate Catalog

Fergal Mullally Jeffrey Coughlin Susan E, Thompson Jessie, Christiansen Christopher Burke Bruce Clarke Michael R, Haas

Published in arXiv preprint arXiv:1602.03204

We present a new automated method to identify instrumental features masquerading as small, long period planets in thecandidate catalog. These systematics, mistakenly identified as planet transits, can have a strong impact on occurrence rate calculations because they cluster in a region of parameter space where Kepler s sensitivity to planets is poo...

The Last Possible Outposts for Life on Mars.

Davila, Alfonso F Schulze-Makuch, Dirk

Published in Astrobiology

The evolution of habitable conditions on Mars is often tied to the existence of aquatic habitats and largely constrained to the first billion years of the planet. Here, we propose an alternate, lasting evolutionary trajectory that assumes the colonization of land habitats before the end of the Hesperian period (ca. 3 billion years ago) at a pace si...

Draft Genome Sequence of Janthinobacterium sp. Ant5-2-1, Isolated from Proglacial Lake Podprudnoye in the Schirmacher Oa...

Koo, Hyunmin Strope, Bailey M Kim, Eddy H Shabani, Adel M Kumar, Ranjit Crowley, Michael R Andersen, Dale T Bej, Asim K

Published in Genome announcements

Janthinobacterium sp. Ant5-2-1, isolated from the Schirmacher Oasis of East Antarctica, produces a purple-violet pigment, manifests diverse energy metabolism abilities, and tolerates cold, ultraviolet radiation, and other environmental stressors. We report here the 6.19-Mb draft genome of strain Ant5-2-1, which will help understand its survival mec...

Solar System Observations with the James Webb Space Telescope

Norwood, James Hammel, Heidi Milam, Stefanie Stansberry, John Lunine, Jonathan Chanover, Nancy Hines, Dean Sonneborn, George Matthew Tiscareno Brown, Michael ...

Published in Publications of the Astronomical Society of the Pacific

The James Webb Space Telescope (JWST) will enable a wealth of new scientific investigations in the near-and mid-infrared, with sensitivity and spatial/spectral resolution greatly surpassing its predecessors. In this paper, we focus upon Solar System science facilitated by JWST, discussing the most current information available concerning JWST instr...
