The Pioneer Anomaly
Jose A. de Diego, Dario Nunez
Analysis of the radio-metric data from Pioneer 10 and 11 spacecrafts has indicated the presence of an unmodeled acceleration starting at 20 AU, which has become known as the Pionee…
The Anomalous Acceleration of the Pioneer Spacecrafts
Jose A. de Diego
Radiometric data from the Pioneer 10 and 11 spacecrafts have revealed an unexplained constant acceleration of a_A = (8.74 +/- 1.33) x 10^(-10) m s^(-2) towards the Sun, also known…
Quasar 3C298: a test-case for meteoritic nanodiamond 3.5 microns emission
J. A. de Diego, L. Binette, P. Ogle +3
We calculate the dust emission expected at 3.43 and 3.53 microns if meteoritic (i.e. hydrogenated) nanodiamonds are responsible for most of the far-UV break observed in quasars. We…
Physical parameters and classification of eight galactic nuclei from the Second Byurakan Survey
Jose A. de Diego
Spectroscopic observations with a resolution of 4.5 Angst were performed for a sample of eight galactic nuclei extracted from the Second Byurakan Survey, and one companion galaxy o…
Dust and the far-UV spectral energy distribution of quasars
Luc Binette, Yair Krongold, Gladis Magris Crestini +1
The spectral energy distribution of quasars shows a sharp steepening of the continuum shortward of ~ 1100 A. We present a new dust extinction model consisting of crystalline carbon…
Pioneer anomaly? Gravitational pull due to the Kuiper belt
Jose A. de Diego, Dario Nunez, Jesus Zavala
In this work we study the gravitational influence of the material extending from Uranus orbit to the Kuiper belt and beyond on objects moving within these regions. We conclude that…
