Discussion Overview

The discussion revolves around capturing star spectra for astronomical analysis, focusing on the methods and equipment needed to obtain real star spectra, as well as the implications of temperature on spectral characteristics. The scope includes practical advice for a project in astronomy and the theoretical understanding of star spectra.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant expresses uncertainty about how to capture star spectra and requests advice on necessary equipment.
  • Another participant suggests simulating star spectra using light bulbs, emphasizing the relationship between a star's temperature and its spectrum.
  • A similar point is reiterated regarding the temperature of stars and the exclusion of extremely hot stars for simulation purposes.
  • A later reply seeks clarification on obtaining real star spectra for deriving information about composition, speed, and direction, indicating a desire for more advanced methods beyond simulations.

Areas of Agreement / Disagreement

Participants do not reach a consensus on how to capture real star spectra, with some focusing on simulations and others seeking methods for actual spectral analysis.

Contextual Notes

Participants have not specified the limitations of their proposed methods or the assumptions underlying their suggestions, such as the feasibility of capturing spectra without advanced equipment.

I'm doing a project about astronomy. I've never done one, I just jumped from quantum physics to here, so I don't think I know anything =.=. To start, I think I need some stars spectrum, but since stars are not as bright as the sun, I don't really know how to have them. Could someone give me some advice of how to have stars spectrum (without using internet), and what equipment do I need...? Thank you very much ^^

The spectrum of a star is based on temperature. You can simulate it with light bulbs: do some research on the different types of stars and their temperatures, then compare them to different types of light bulbs and their temperatures.

There are stars that are millions of temperature. Exclude them before doing some simulation.
 
Thanks ^^. But I mean the real star spectrum where I can derive the composition of the stars, speed, directions... Is that possible...?
