Journal ArticleDOI

Characteristics of planetary candidates observed by Kepler. II. Analysis of the first four months of data

William J. Borucki, +69 more
TL;DR: In this article, the Kepler mission released data for 156,453 stars observed from the beginning of the science observations on 2009 May 2 through September 16, and there are 1235 planetary candidates with transit-like signatures detected in this period.
Journal ArticleDOI

Airborne Spectrophotometry of SN 1987A from 1.7 to 12.6 Microns: Time History of the Dust Continuum and Line Emission

TL;DR: In this paper, the low-resolution (lambda/Delta lambda = 50-100) spectra of SN 1987A are combined with data from other wavelengths to model the continuum, subtract the continuum from the spectra to determine line strengths and reveal molecular bands, separate the atomic continuum radiation from the dust continuum, and derive constraints on the grain temperatures and optical depths.
Journal ArticleDOI

Thermal emission spectra of Mars (5.4–10.5 μm): Evidence for sulfates, carbonates, and hydrates

TL;DR: In this article, the authors reported that the sulfate and carbonate-bearing minerals are contained in the same particles of airborne dust as the dominant silicate minerals, and that the dust optical depth is about 0.6 at a reference wavelength of 0.3 micron over the area of the observed spots.
Journal ArticleDOI

The infrared emission bands. I - Correlation studies and the dependence on C/O ratio

TL;DR: In this article, airborne measurements of unknown IR (UIR) 5-8 micron emission bands of eight planetaries, eight locations in five reflection nebulae, and seven locations in four H II regions (including the Orion Bar), are presently compared with existing and new ground-based observations of the 3.3, 8.7, and 11.3 micron bands.
