User Guidelines
To use the Microlensing Calculator effectively, follow these steps:
- Input the Lens Mass: Enter the mass of the lensing object in solar masses (e.g., 1.0 for a star like the Sun).
- Specify Distances: Provide the distances from the observer to the lens, observer to the source, and lens to the source in parsecs. Ensure these values are consistent (e.g., \( D_{LS} \leq D_S \)).
- Enter the Impact Parameter: Input the dimensionless impact parameter \( u \), which represents the closest approach of the source to the lens in units of the Einstein radius.
- Calculate: Click the "Calculate" button to compute the Einstein radius (in arcseconds) and magnification.
- Review Results: The results will display the Einstein radius and magnification, along with an interpretation of the lensing effect.
Tip: Ensure all inputs are positive numbers, and double-check distance values for physical consistency. For example, the lens-to-source distance should not exceed the observer-to-source distance.
Scientific Foundations
The Microlensing Calculator is grounded in the principles of general relativity, specifically the bending of light by a massive object. The Einstein radius, a key output, defines the angular scale of the lensing effect and is derived from the lens equation. The magnification formula accounts for the amplification of a background star's light as it passes near the lens. These calculations are based on well-established astrophysical models, ensuring that the tool provides accurate and reliable results for real-world applications.
