Charge

That stellar wind might be neutrally charged could require a bit of elaboration as well as a reliable source. --Harald Khan Ճ 14:35, 6 December 2008 (UTC)

Stellar Wind

The code name for the National Security Agency (NSA) collection activities that were previously unknown to all but a tiny number of officials at the White House and in the U.S. intelligence community was referred to as Stellar Wind. —Preceding unsigned comment added by Ladoo37 (talk • contribs) 04:12, 17 December 2008 (UTC)

That article got nothing to do with this one; thus a reference should not be added under the 'see also' section as it is completely irrelevant. If the article survives, a reference could be added at the start of the article, like for example here. --Harald Khan Ճ 13:39, 17 December 2008 (UTC)

"Stellar Wind"

The usage of Stellar Wind (edit | talk | history | protect | delete | links | watch | logs | views) is under discussion, see talk:Stellar Wind (code name) -- 70.50.148.122 (talk) 06:50, 26 January 2014 (UTC)

Velocities

Seems a bit odd that slow winds have (v = 10 km/s) whereas very high velocities (v > 1–2000 km/s). If "slow" is 10 how can "very high" include "slow" in its range? Vsmith (talk) 15:55, 26 January 2014 (UTC)

Speculating here, but perhaps "1-2000 km/s" was meant to mean "1000-2000 km/s". I haven't changed it because I haven't confirmed this from reliable sources, but it seems reasonable. --Yaush (talk) 15:06, 27 January 2014 (UTC)

Digressive source

Ref 1, "Dust Envelopes" doesn't refer to or explain how pressure of light can overcome the gravity of the star. Unless a more relevant source can be referred to, the concerned statement should be removed or at least worded as speculative. — Preceding unsigned comment added by As110 (talk • contribs) 17:22, 8 April 2014 (UTC)

It's basic physics and not at all mysterious. Light carries momentum. A sufficiently strong outward flow of radiation can deposit enough momentum in dust to overcome gravity. This is completely noncontroversial, textbook stuff. --Yaush (talk) 17:58, 8 April 2014 (UTC)

Spare me the peremptory attitude. Not collimated particle streams, the article only refers to isometric dust shells. -- As110 (talk) 18:23, 8 April 2014 (UTC)

It's still basic textbook stuff. Not the least speculative. --Yaush (talk) 18:46, 8 April 2014 (UTC)

Thank you for displaying your ignorance on the matter, Yaush. Now please present some sources on the specific matter, including of course the acceleration of the collimated streams. -- As110 (talk) 19:07, 8 April 2014 (UTC)

The short article could use more references. If unsourced material is questionable, the proper approach is to A: find and add references, or B: add a citation needed tag to the questioned content. Simply removing the information and adding your own unsourced commentary to the article ("though it's undetermined how pressure of light can overcome the gravity of the star") is not acceptable. Also, please assume good faith and avoid making negative comments about your fellow editors. Vsmith (talk) 19:57, 8 April 2014 (UTC)

Thank you, VSmith. The statement being sourced is that the massive winds of red giants and supergiants are driven by radiation pressure on dust grains in their outer atmospheres. The source I added to support this utterly noncontroversial statement of the general consensus is a university web page that talks about how dust in red giant and supergiant atmospheres is an efficient absorber of radiation momentum, which dominates the dynamics. I don't understand why the statement in this article is at all controversial to anyone the least familiar with the field, and why the source is not thought to be supporting the statement. Since collimated streams are not mentioned either in the article or the source, I'm not sure why As110 is bringing it up. --Yaush (talk) 20:04, 8 April 2014 (UTC)

Being "not sure" is usually accompanied with being humble, except for some wikipedia editors it seems. Collimated stellar winds exist, and ESA doesn't know how they work, maybe you should call them and say that it's basic textbook stuff: http://sci.esa.int/solar-orbiter/51169-what-drives-the-solar-wind-and-where-does-the-coronal-magnetic-field-originate-from/ ... But no point in arguing since you have clearly made up your mind already, so I'm not gonna waste any more of my time and just leave this as another example why editing wikipedia is awful. -- As110 (talk) 01:37, 9 April 2014 (UTC)

The solar wind is not a massive cool dusty wind. Complete different phenomenon. The fact you don't know the difference between the solar wind and a massive cool dusty wind from a red supergiant suggests we are, indeed, wasting our time arguing: You don't know what you're talking about and you aren't going to let anyone educate you. WP:CIR seems to apply here. --Yaush (talk) 02:36, 9 April 2014 (UTC)

Yeah I'm sure you got all the facts straight. :) Keep following your WP:BS rules. -- As110 (talk) 08:34, 9 April 2014 (UTC)

Stellar Wind's affect on planets in the habitable zone

I came here from Proxima_Centauri_b and just thought there might be some helpful if there a section that covers why the concept of the solar wind being 2000x more powerful makes a planet in the Circumstellar_habitable_zone likely not viable for life--nor can it be ruled out. Is it heat? Damage to the atmosphere? Shard of floating plasma flying around? Be nice to have some context if there are different levels of impacts by solar winds collide with celestial objects. 73.212.169.23 (talk) 03:12, 21 July 2018 (UTC)

Compensation for the loss of mass of the star

The loose volume of space vacuum and ether of the universe increases by the relative value of twice the Volume Constant of Hubble (2*6,591*$10^{-18}$ per second) as a result of the process of being a dense volume of space of substance. Already existing neutrons, protons, atomic nuclei, and electrons generate and emit outward streams of vortices-strings of a loose volume of the space of electrostatics and magnetism. This is the action of the physical mechanism of the microscopic big bang, the birth of a loose volume in the space of vacuum and ether from the dense volume of the space of substance. In the magnitude of half of the increasing volume of the space of the vacuum and the ether of the universe, the chaos of vortices-strings of electrostatics and magnetism in portions of ~ 3.5 cubic meters-self-focuses and is very strongly compressed into new atomic units of mass in the form of new neutrons occupying a volume of space of ~$10^{-45}$ cubic meters. This is the action of the physical mechanism of the microscopic large collapse of half of the growing non-dense volume of the space of vacuum and ether into the dense volume of the space of substance. Over the course of a year, the mass of the Sun's star increases by ~ two ten-billionths of a billion. With a doubling period of ~ 3.3325 billion years. Therefore, stars of the Sun class do not decrease in mass, but rather increase in mass. 95.27.231.251 (talk) 07:21, 6 June 2021 (UTC)
