Report for the Academic Year 1995
Institute /or ADVANCED STUDY REPORT FOR THE ACADEMIC YEAR 1994 - 95 PRINCETON NEW JERSEY Institute /or ADVANCED STUDY REPORT FOR THE ACADEMIC YEAR 1 994 - 95 OLDEN LANE PRINCETON • NEW JERSEY 08540-0631 609-734-8000 609-924-8399 (Fax) Extract from the letter addressed by the Founders to the Institute's Trustees, dated June 6, 1930. Newark, New jersey. It is fundamental in our purpose, and our express desire, that in the appointments to the staff and faculty, as well as in the admission of workers and students, no account shall be taken, directly or indirectly, of race, religion, or sex. We feel strongly that the spirit characteristic of America at its noblest, above all the pursuit of higher learning, cannot admit of any conditions as to personnel other than those designed to promote the objects for which this institution is established, and particularly with no regard whatever to accidents of race, creed, or sex.

Recycling' a Star (W/Animations) 21 May 2009
The cosmos is green: Researchers catch nature in the act of 'recycling' a star (w/Animations) 21 May 2009 survey has found many new pulsars, but this one is truly special -- it is a very freshly 'recycled' pulsar that is emerging straight from the recycling plant." said Archibald. The McGill researchers worked with Asst. Prof. Ingrid Stairs of UBC and Scott Ransom of NRAO as well as others from the collaboration to carry out more observations of this unusual pulsar. Pulsars are rapidly rotating, highly magnetized neutron stars, the remnants left after massive stars have exploded as supernovae. Pulsars emit lighthouse-like beams of radio waves that sweep around as the star rotates. Most rotate relatively Neutron star with accretion disk (left) drawing material slowly, ten times a second or less, and their from companion star (right). CREDIT: Bill Saxton, magnetic fields ordinarily slow them down even NRAO/AUI/NSF further over the course of millennia. Millisecond pulsars, however, rotate hundreds of times a second. (PhysOrg.com) -- For the first time, researchers "We know normal pulsars typically pulsate in the have observed a singular cosmic act of rebirth: the radio spectrum for one million to ten million years, transformation of an ordinary, slow-rotating pulsar but eventually they slow down enough to die out," into a superfast millisecond pulsar with an almost explained Kaspi. "But a few of these old pulsars get infinitely extended lifespan. 'recycled' into millisecond pulsars. They end up spinning extremely fast, and then they can pulsate The discovery was made during a large radio sky forever. -
The Onset of Chaos in Permanently Deformed Binaries from Spin–Orbit and Spin–Spin Coupling

The Onset of Chaos in Permanently Deformed Binaries from Spin–Orbit and Spin–Spin Coupling Darryl Seligman1 and Konstantin Batygin2 1 Dept. of the Geophysical Sciences, University of Chicago, Chicago, IL 60637, USA; [email protected] 2 Division of Geological and Planetary Sciences, Caltech, Pasadena, CA 91125, USA Received 2020 September 16; revised 2021 March 22; accepted 2021 March 24; published 2021 May 21 Abstract Permanently deformed objects in binary systems can experience complex rotation evolution, arising from the extensively studied effect of spin–orbit coupling as well as more nuanced dynamics arising from spin–spin interactions. The ability of an object to sustain an aspheroidal shape largely determines whether or not it will exhibit nontrivial rotational behavior. In this work, we adopt a simplified model of a gravitationally interacting primary and satellite pair, where each body’s quadrupole moment is approximated by two diametrically opposed point masses. After calculating the net gravitational torque on the satellite from the primary, as well as the associated equations of motion, we employ a Hamiltonian formalism that allows for a perturbative treatment of the spin–orbit and retrograde and prograde spin–spin coupling states. By analyzing the resonances individually and collectively, we determine the criteria for resonance overlap and the onset of chaos, as a function of orbital and geometric properties of the binary. We extend the 2D planar geometry to calculate the obliquity evolution. This calculation indicates that satellites in spin–spin resonances undergo precession when inclined out of the plane, but they do not tumble. -

The collision speed is one of the parameters, that serves as a proxy to a collisional outcome e.g., complete disruption and scattering of fragments, or formation of crater, where both processes are directly related to the impact energy. We utilize an improved and de-biased model of the trans-Neptunian object (TNO) region from the \Outer Solar System Origins Survey" (OSSOS). -

Abstract. The fastest pulsar and the slowest nova; the oldest galaxies and the youngest stars; the weirdest life forms and the commonest dwarfs; the highest energy particles and the lowest energy photons. These were some of the extremes of Astrophysics 2006. We attempt also to bring you updates on things of which there is currently only one (habitable planets, the Sun, and the universe) and others of which there are always many, like meteors and molecules, black holes and binaries.
