Astronomers using National Science Foundation radio telescopes have demonstrated how a combination of gravitational-wave and radio observations, along with theoretical modeling, can turn the mergers o...
‘Upside-down planet’ reveals new method for studying binary star systems
Upside-down planet reveals new method studying binary star systems
2014/5/13
What looked at first like a sort of upside-down planet has instead revealed a new method for studying binary star systems, discovered by a University of Washington student astronomer.
New Method for Exploring Super-Eddington AGNs by Near-infrared Observations
accretion: accretion disc—black hole physics— galaxies:active
2011/10/8
We propose a new method to explore the candidate super-Eddington active galactic nuclei (AGNs). We examine the properties of infrared (IR) emission from the inner edge of the dusty torus in AGNs, whic...
A method is presented here for investigating variations in the upper end of the stellar Initial Mass Function (IMF) by probing the production rate of ionizing photons in unresolved, compact star clust...
A New Method to Identify Nearby, Young, Low-mass Stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
We describe a new method to identify young, late-type stars within ~150 pc of the Earth that employs visual or near-infrared data and the GALEX GR4/5 database. For spectral types later than K5, we dem...
A New Method for Determining Geometry of Planetary Images
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/27
This paper presents a novel semi-automatic image processing technique to estimate accurately, and objectively, the disc parameters of a planetary body on an astronomical image.
