Physical characterization of hyperbolic comet C/2017 U7
We present here observations of the comet C/2017 U7 obtained in 2018 and 2019 using the red camera of Goodman High Throughput Spectrograph (GHTS) at SOAR...
Physical characterization of near-Earth asteroid (159402) 1999 AP10 in support of the Arecibo Planetary Radar Program within the NEOROCKS project.
. The near-Earth object (NEO) population is composed of asteroids and comets that have orbits close to the Earth. This population is the most accesible vestige...
Physical characterization of near-Earth objects from the IMPACTON project
IntroductionAsteroids lightcurves have been used extensively to derive many important physical characteristics such as rotational properties (rotational period...
Physical conditions in NGC 6543 from ISO and HST data and the pitfalls of temperature maps
We determine the physical conditions in NGC 6543, obtaining two different estimates of the electron temperature (T[e]) and one estimate of the electron density...
Physical Conditions in the Partially Ionized Zone of the Orion Nebula
We report the first reliable measurement of the nebular [O i] λ 5577 Angstroms emission line in the Orion nebula. Diagnostic diagrams based on the 5577 [O i]...
