The applicability of the third integral of motion: Some numerical experiments
Michel Henon,Carl Heiles +1 more
TL;DR: In this paper, the existence of a third isolating integral of motion in an axisymmetric potential was investigated by numerical experiments and it was found that the third integral exists for only a limited rage of initial conditions.
Journal ArticleDOI
The bell laboratories H I survey
Antony A. Stark,Antony A. Stark,Charles F. Gammie,Robert W. Wilson,John Bally,R. A. Linke,Carl Heiles,Mark Hurwitz +7 more
TL;DR: In this article, the authors present a galactic survey which to date consists of 73,000 positions covering −5° < l < 122°, −1° < b < 1°, observed in the J=1 → 0 line of 13CO to an rms noise level of 0.15 K in 0.68 km s−1 channels, using the 7 m antenna at Crawford Hill.
Journal ArticleDOI
A millisecond pulsar
TL;DR: The puzzle of the radio properties of 4C21.53 may be resolved by the discovery and related observations of a fast pulsar, 1937+214, with a period of 1.558 ms in the constellation Vulpecula only a few degrees from the direction to the original pulsar.
Journal ArticleDOI
The Millennium Arecibo 21 Centimeter Absorption-Line Survey. II. Properties of the Warm and Cold Neutral Media
Carl Heiles,Thomas H. Troland +1 more
TL;DR: In this article, the authors used principal components analysis, together with a form of least-squares fitting that accounts for errors in both the independent and dependent parameters, to discuss the relationships among the four CNM Gaussian parameters.
Journal ArticleDOI
The Millennium Arecibo 21-CM Absorption Line Survey. II. Properties of the Warm and Cold Neutral Media
Carl Heiles,Thomas H. Troland +1 more
TL;DR: In this article, the authors used principal components analysis (PCA) and a form of least squares fitting (LSA) to analyze the properties of the warm and cold neutral media (WNM) in the Solar neighborhood.
