Journal ArticleDOI
IS DUST FORMING ON THE RED GIANT BRANCH IN 47 Tuc
Martha L. Boyer,Jacco Th. van Loon,Iain McDonald,Karl D. Gordon,Brian Babler,Miwa Block,S. Bracker,Charles W. Engelbracht,Joseph L. Hora,Remy Indebetouw,Marilyn R. Meade,Margaret Meixner,Karl Misselt,Marta Sewilo,Bernie Shiao,Barbara A. Whitney +15 more
TL;DR: Using Spitzer IRAC observations from the SAGE-SMC Legacy program and archived SpitzerIRAC data, this paper investigated dust production in 47Tuc, a nearby massive Galactic globular cluster.
Journal ArticleDOI
The size and albedo of Rosetta fly-by target 21 Lutetia from new IRTF measurements and thermal modeling
TL;DR: In this article, the M-type asteroid 21 Lutetia has a primitive, carbonaceous-chondrite-like (C-type) surface composition for which a low geometric albedo would be expected; this is incompatible with the IRAS albedos of 0.221+/- 0.020.
Journal ArticleDOI
A spatially resolved study of photoelectric heating and (C II) cooling in the LMC Comparison with dust emission as seen by SAGE
D. Rubin,Sacha Hony,S. C. Madden,Alexander G. G. M. Tielens,Margaret Meixner,Remy Indebetouw,William T. Reach,Adam Ginsburg,Sungeun Kim,K. Mochizuki,Brian Babler,Miwa Block,S. Bracker,Charles W. Engelbracht,B. Q. For,Karl D. Gordon,Joseph L. Hora,Claus Leitherer,Marilyn R. Meade,Karl Misselt,Marta Sewilo,U. Vijh,B. A. Whitney +22 more
TL;DR: In this article, the authors quantify the importance of the [C II] cooling line and the photoelectric heating process of various environments in the LMC and investigate which parameters control the extent of photoelectric heat.
Journal ArticleDOI
Deep mid-infrared observations of lyman break galaxies
Pauline Barmby,J.-S. Huang,Giovanni G. Fazio,Jason Surace,R. G. Arendt,Joseph L. Hora,M. A. Pahre,K. L. Adelberger,Peter R. Eisenhardt,Dawn K. Erb,Max Pettini,William T. Reach,Naveen A. Reddy,Alice E. Shapley,Charles C. Steidel,Daniel Stern,Zhong Wang,Steven Willner +17 more
TL;DR: The results of the model fitting show that previous optical/near-infrared studies of LBGs were not missing large, hidden old stellar populations as mentioned in this paper, and the LBG candidates' properties are consistent with those of massive star-forming galaxies at z ~ 3.
Journal ArticleDOI
Spitzer 24 um Images of Planetary Nebulae
You-Hua Chu,Robert A. Gruendl,Martín A. Guerrero,Kate Y. L. Su,Jana Bilikova,Martin Cohen,Quentin A. Parker,Kevin Volk,A. Caulet,Wen Ping Chen,Joseph L. Hora,Thomas Rauch +11 more
TL;DR: In this paper, the authors used the Spitzer MIPS 24 um images for 36 Galactic planetary nebulae (PNe) whose central stars are hot white dwarfs (WDs) or pre-WDs with effective temperatures of ~100,000 K or higher.
