THE PULSAR PLANETS: A TEST CASE OF TERRESTRIAL PLANET ASSEMBLY [PDF]

The Astrophysical Journal, 2009
We model the assembly of planets from planetary embryos under the conditions suggested by various scenarios for the formation of the planetary system around the millisecond pulsar B1257+12. We find that the most likely models fall at the low angular momentum end of the proposed range.

MEASURING THE MASS OF SOLAR SYSTEM PLANETS USING PULSAR TIMING [PDF]

AIP Conference Proceedings, 2010
High-precision pulsar timing relies on a solar-system ephemeris in order to convert times of arrival (TOAs) of pulses measured at an observatory to the solar system barycenter. Any error in the conversion to the barycentric TOAs leads to a systematic variation in the observed timing residuals; specifically, an incorrect planetary mass leads to a ...

Scientific Error and Error Handling

Scientonomy, 2021
Error is a common part of scientific practice, which must be accounted for by scientonomy. A scientific error occurs when an agent accepts a theory that should not have been accepted given that agent’s employed method. One might suspect that the handling

Machine Learning in Astrophysics: A Multi-Algorithm Comparison for Pulsar Prediction [PDF]

EPJ Web of Conferences
Pulsar stars were discovered over 50 years ago. Known for their radiation pulses observed at regular intervals from planet Earth, they are a type of neutron star that possesses extremely powerful magnetic fields which are a result of the collapsed cores ...
