PublicationUsing Globular Clusters to Test Newton's Law of Gravity
New measurements of the velocity dispersion of the globular cluster ω Centauri allow us to trace its gravitational potential down to an acceleration of 8×10-9...

PublicationUsing Kepler K2 to Measure the Binary Fraction of PN Central Stars
During the initial Kepler mission, 5 Planetary Nebula (PN) central stars were observed. The light curves for 4 of these central stars indicated a history of...

PublicationUsing PNe to Explore the History of M31's Extended Disk
The results of O/H abundances derived from PNe in M31 (accompanying poster by Hensley et al.) have extended the radius coverage of our previous gradient studies...

PublicationUsing reduction and inversion tools for THEMIS-MTR data: chromospheric reversals of a moving magnetic feature and an ephemeral region .
New tools have been developed for THEMIS spectropolarimetric data. In this paper we present how these tools work and can be used in order to understand two...

PublicationUsing symmetries and generating functions to calculate and minimize moments of inertia
This paper presents some formulae to calculate moments of inertia for solids of revolution and for solids generated by contour plots. For this, the symmetry...
