Accretion rate onto a WD over time (relation)

Click For Summary

Discussion Overview

The discussion revolves around the relationship between the accretion rate onto a white dwarf (WD) and time. Participants explore whether there is a correlation, particularly considering the hypothesis that the accretion rate may decrease as time increases. The inquiry is framed as a general technical question rather than a homework-related issue.

Discussion Character

  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant proposes that the accretion rate onto a white dwarf should decrease over time, but they are uncertain about the specific correlation.
  • Another participant seeks clarification on the abbreviation "WD," confirming it stands for white dwarf.
  • There is an inquiry about whether the discussion is homework-related or a general technical question, with participants clarifying that it is driven by curiosity.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the correlation between accretion rate and time, and the discussion remains exploratory with multiple viewpoints expressed.

Contextual Notes

The discussion lacks specific references or links to existing literature on the topic, and assumptions about the nature of the accretion process have not been fully articulated.

Hi all, I was wondering if there is a correlation between the accretion rate and time. I think it should decrease as time increases, but I can't find the right correlation

Welcome to the PF.

What's a "WD"? White Dwarf?

and thank you :-)
 
Great, thanks. Is this mainly homework of some kind, or is it a more general technical question? I can move it to the technical PF forums if it's a more general question. Also, what have you found in your searching so far? Can you post some links to your reading? Thanks.

it's not for homework. just curiosity :-)
 
Fair enough. I'll move this thread to the Astro forum. Please post links to the reading you have been doing on this so far. Thanks.
