Overview

SPV

Calculates a stars position and velocity in the cartesian coordinate system.

Todo

Expand the number of available operation
Batch processing by taking file inputs
Rust crate version
Organizing/file structure options for batch output
The ability to forward information from input files to the output files (example: Luminosity)

What it can't do

Get any radial velocity if the position is 0
Yeah that's about it :)

Governing equations

Position

Where x, y and z are the coordinates in the cartesian coordinate system in [km].

ra is Right ascension in [degrees] and dec is Declination in [degrees]

Radial velocity

x_u, y_u and z_u are the coordinates for a unitvector pointing in the direction of the Radial Velocity vector.

Removing the 0's is used for positive Radial Velocity vectors.

x, y and z are still the position coordinates in cartesian coordinates [km].

Multiplying by the radial velocity gives us the coordinates of the resulting vector.

Proper motion

Getting the position the object will be at in one second by using the same formula as for position.

Resetting the origin of the vector to the current position

Multiplying by the new position gives us the coordinates of the resulting vector.

Total velocity

Just taking the sum of the two velocities.

Comments

Fixed angle error and added pos from t_p

Velocity equations used the eccentric anomaly (E) when the true anomaly (v) should have been used instead. This pull request addresses that problem. Additionally, it allows for the current position along the orbit to be calculated using the time since periapsis (t_p).

opened by HolmanDev 3
Reverted atan2 change

The previous atan2 change was unnecessary and wrong. It was thought that the true anomaly would be constrained to a maximum of 90 degrees, but this wasn't true because the equation multiplied the result by two, resulting in a full -180 to 180 degree range.
