The Data

In particular, there is focus on the P/P-dot diagram that contains the data that shows the known set of radio pulsars, which include some isolated x-ray pulsars, along with some binary millisecond pulsars.

This chapter describes the data sources that are being used as the context from which the NS-Capture Theory is derived.

These data sources include the following:

• The P/P-dot Diagram: Classification of the Pulsars.
  (This page describes the data in the P/P-dot diagram)
• The P/P-dot Diagram and How NS-Capture Theory explains it.
  (This data diagram shows the spin rate and spin rate change of most of the spinning-down pulsars that have been measured since 1967.
  NS-Capture Theory has a new way to explain the major characteristics of this diagram)
• P/P-dot empirical evidence for NS-Capture.
  (This page explains how the P/P-dot diagram implicitly leads to NS-Capture as physical explanation behind the data.)
• Cen X-3: The Pulsar Spin Contradiction.
  (This page describes the data from Cen X-3 (the 1st binary x-ray pulsar) that is critical for understanding NS-Capture)
• Her X-1: The 2nd binary x-ray pulsar.
  (Her X-1 is “the intermediary between supergiants and millisecond pulsars” and empirically connects the whole thing)
• Millisecond Pulsars.
  (Pulsars, many in binary systems that spin hundreds of times per second)
• Be/X-ray Binary General Data.
  (Overview of the systems that are “between” Cen X-3 and Her X-1: i.e. giants w NS that are just below the supergiant w NS class)
  • List of refs for Be/X-ray Binary Data Collections.
    (A list of data refs along w google search expressions to find them)
• Be/X-ray Binary Spin-Orbit Data.
  (NS-Capture Theory predicted this data would be found long before it was discovered as this page explains)
• What about the Double Pulsar?

Since the conventional P/P-dot diagram only contains pulsars that are spinning down (pulsing slower with time), we describe how the spinning up pulsars can be used on a complementary negative P-dot graph that shows the spin up evolution similar to the main P/P-dot spin-down evolution.

In order to show the spin up evolution, data is presented from the binary x-ray pulsars Cen X-3 and Her X-1, plus additional data regarding the Be X-ray Binaries (BeXB’s).

Finally, consideration is given to how the millisecond pulsars (MSP’s), which are known to have either a slow spin-up property or a slow spin-down property and can appear on either the positive or negative half of the full P/P-dot diagram.Plus, there is a page discussing the concept of a Double Pulsar Binary (DPB).
