The Dependence of Protostellar Luminosity on Environment in the Cygnus-X Star-forming Complex
E. Kryukova,S. T. Megeath,Joseph L. Hora,Robert A. Gutermuth,Sylvain Bontemps,Kathleen E. Kraemer,Martin Hennemann,Nicola Schneider,Howard A. Smith,Frédérique Motte +9 more
TL;DR: In this paper, the authors compare the luminosity functions of two regions within Cygnus-X: CygX-South and Cyg X-North, and find that the luminosities of these two regions are statistically different.

S-CANDELS: The Spitzer-Cosmic Assembly Near-Infrared Deep Extragalactic Survey. Survey Design, Photometry, and Deep IRAC Source Counts
M. L. N. Ashby,Steven P. Willner,Giovanni G. Fazio,James S. Dunlop,Eiichi Egami,S. M. Faber,Henry C. Ferguson,Norman A. Grogin,Joseph L. Hora,Jiasheng Huang,Anton M. Koekemoer,Ivo Labbé,Zheng Wang +12 more
TL;DR: The Spitzer-Cosmic Assembly Deep Near-Infrared Extragalactic Legacy Survey (S-CANDELS; PI G. Fazio) is a Cycle 8 Exploration Program designed to detect galaxies at very high redshifts (z > 5) as discussed by the authors.
Journal ArticleDOI
Fundamental parameters, integrated red giant branch mass loss, and dust production in the galactic globular cluster 47 tucanae
Iain McDonald,Martha L. Boyer,J. Th. van Loon,Albert A. Zijlstra,Joseph L. Hora,Brian Babler,Miwa Block,Karl D. Gordon,Marilyn R. Meade,Margaret Meixner,Karl Misselt,Thomas P. Robitaille,Marta Sewilo,Bernie Shiao,B. A. Whitney +14 more
TL;DR: In this article, spectral energy distributions (SEDs) were used to identify those stars that exhibit infrared excess, finding excess only among the brightest giants: dusty mass loss begins at a luminosity of ~1000 L ☉, becoming ubiquitous above L = 2000 L
Journal ArticleDOI
Polar lightning and decadal-scale cloud variability on Jupiter.
Kevin H. Baines,Amy A. Simon-Miller,Glenn S. Orton,Harold A. Weaver,Allen W. Lunsford,Thomas W. Momary,John R. Spencer,Andrew F. Cheng,Dennis C. Reuter,Donald E. Jennings,G. R. Gladstone,Jeffrey M. Moore,S. Alan Stern,Leslie A. Young,Henry B. Throop,Padma Yanamandra-Fisher,Brendan Fisher,Joseph L. Hora,Michael E. Ressler +18 more
TL;DR: Optical observations from the New Horizons spacecraft have identified lightning at high latitudes above Jupiter up to 80°N and 74°S, demonstrating that vertical dynamical processes are time-varying on seasonal scales at mid- and low latitudes on Jupiter.

Fundamental parameters, integrated RGB mass loss and dust production in the Galactic globular cluster 47 Tucanae
Iain McDonald,Martha L. Boyer,Jacco Th. van Loon,Albert A. Zijlstra,Joseph L. Hora,Brian Babler,Miwa Block,Karl D. Gordon,Marilyn R. Meade,Margaret Meixner,Karl Misselt,Thomas P. Robitaille,Marta Sewilo,Bernie Shiao,Barbara A. Whitney +14 more
TL;DR: In this paper, spectral energy distributions (SEDs) were used to identify those stars which exhibit infrared excess, finding excess only among the brightest giants: dusty mass loss begins at a luminosity of ~ 1000 Lsun, becoming ubiquitous above 2000 Lsun.
