Adaptive optics is a prime example of how progress in observational astronomy can be
driven by technological developments. At many observatories it is now considered to be part …

ABSTRACT The Keck Observatory began science observations with a laser guide star
adaptive optics system, the first such system on an 8–10 m class telescope, in late 2004 …

Context. Until recently, the 3D shape, and therefore density (when combining the volume
estimate with available mass estimates), and surface topography of the vast majority of the …

Non-destructive, non-contaminating, and relatively simple procedures can be used to
measure the bulk density, grain density, and porosity of meteorites. Most stony meteorites …

The number of asteroids with accurately determined orbits increases fast, and this increase
is also accelerating. The catalogs of asteroid physical observations have also increased …

We compiled a list of estimated parameters of binary systems among asteroids from near-
Earth to trojan orbits. In this paper, we describe the construction of the list, and we present …

Abstract The TMT Detailed Science Case describes the transformational science that the
Thirty Meter Telescope will enable. Planned to begin science operations in 2024, TMT will …

In the past decade, the number of known binary near-Earth asteroids has more than
quadrupled and the number of known large main-belt asteroids with satellites has doubled …

The Trojan population consists of two swarms of asteroids following the same orbit as
Jupiter and located at the L4 and L5 stable Lagrange points of the Jupiter–Sun system …

The Gemini Planet Imager (GPI) has as its science instrument an infrared integral field
spectrograph/polarimeter (IFS). Integral field spectrographs are scientificially powerful but …
