Python astronomy tools for spectroscopic binary system
Project description
Spectroscopic Binary System
Spectroscopic Binary System is a package intended to contain functionality and some common tools needed for performing astrophysics on spectroscopic binary stars with Python. It allows, among other things, to automatically measure the radial velocity of SB1 type systems and to find their orbital solution with BinaryStarSolver (https://github.com/NickMilsonPhysics/BinaryStarSolver)
Installation
mac/unix
pip install spectroscopicbinarysystem
windows
py -m pip install spectroscopicbinarysystem
Usage/Examples
Download sample data (see /examples/alphadra directory)
And run this code :
from spectroscopicbinarysystem import SpectroscopicBinarySystem
sbs = SpectroscopicBinarySystem('hd123299',
'./examples/alphadra/',
t0=2451441.804,
period_guess=51,
debug=True)
# plot result with matplotlib and save the results
sbs.plotRadialVelocityCurve(title="α Dra - HD123299 - Phased radial velocities", savefig=True)
# display result with plotly
sbs.plotlyRadialVelocityCurve(
title="α Dra - HD123299 - Phased radial velocities")
