Do neutron stars, pulsars, magnetars etc. have weather?

Click For Summary

Discussion Overview

The discussion revolves around whether neutron stars, pulsars, magnetars, and similar celestial objects experience phenomena analogous to solar weather, such as solar flares, sunspots, or solar winds. Participants explore various aspects of these objects and their unique characteristics in relation to traditional solar weather concepts.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions if neutron stars and related objects have solar flares, sunspots, or solar winds, seeking clarification on what such phenomena would be called.
  • Another participant asserts that these stars are fundamentally different from the Sun, suggesting that while there are events that could be considered analogous to solar weather, they do not directly correspond to solar phenomena.
  • A participant introduces the concept of starquakes, implying they may be relevant to the discussion of weather-like events in neutron stars.
  • One response challenges the original poster's understanding of starquakes, suggesting they should research the topic further to understand the conditions under which such events occur.
  • Another participant mentions that starquakes could be categorized as weather events, noting their impact on a magnetar's magnetic field.
  • A participant elaborates on the existence of a plasma-filled magnetosphere around neutron stars, indicating that while there are events similar to those in main sequence stars, they are fundamentally different due to the extreme magnetic fields present in neutron stars.
  • This participant also highlights specific phenomena such as pulsar winds and gamma-ray bursts, differentiating them from starquakes and emphasizing the unique conditions of neutron stars.

Areas of Agreement / Disagreement

Participants generally disagree on whether phenomena like starquakes can be classified as weather. While some suggest that certain events may be analogous to solar weather, others maintain that the differences in conditions and characteristics preclude a direct comparison.

Contextual Notes

The discussion reflects varying levels of understanding regarding the mechanisms behind starquakes and other phenomena associated with neutron stars, as well as the definitions of "weather" in this context. There are unresolved assumptions about the nature of these events and their classification.

Do neutron star, pulsars, magnetars etc. have solar flares like the sun or do they have sun spots like the sun or do they have solar winds and if they do have any of those types of weather, what are they called?
 
Astronomy news on Phys.org
These stars are not like the Sun - so the short answer is "no".
There is "stuff that happens on and about them", some of which could be considered as analogous to some solar "weather" stuff ... you should be able to read about them in books and online.
 
How about starquakes?
 
The answers could occupy an entire semester's astrophysics course - what have you don to try to find the answers yourself?
i.e. Do you know what a starquake is and how they happen?
 
I do think star quakes fall in the category of weather but they do hit 23 on the recner scale and can mess up a magnetars magnetic field.
 
So the answer is "no" - you don't know how they happen?
If you want to know if a starquake can happen on a particular class of star you should first learn about them, then see if the conditions exist in some form on the particular class in question.
 
There exists a plasma filled magnetosphere around neutron stars. So, as Simon Bridge says, the answer is no, however there occurs some sort of events similar but not the same as that also occurs in a main sequence star (like sun). For example there are pulsar winds, gamma ray bursts etc. The starquakes are totally different than the magnetospheric events since a starquake occurs as a consequence of crunches of the neutron star crust. The main reason of the answer "no" is that the typical magnetic field of a neutron star is much much higher than a main sequence star (between $10^8-10^{15}$ Gauss). You can study all of this "weather" stuff under the subject of "neutron star magnetosphere", I guess.
