fast-rv 0.1.0

A lightweight toolkit for first-order single-planet radial velocity fitting

FAST-RV

FAST-RV (First-order Automated Single-planet Tool for Radial Velocities) is a lightweight Python toolkit for quickly analyzing exoplanet radial velocity data from VizieR catalogs.

It performs fast first-order Keplerian fitting and produces phase-folded radial velocity curves without going to any complexities of Bayesian inference / MCMC .

Features

• Fetch radial velocity time series from VizieR
• Estimate orbital period
• Fit a simple single-planet Keplerian model
• Generate phase-folded RV plots
• Example workflow for 51 Pegasi b

Installation

Clone the repository and install dependencies:

git clone https://github.com/proxima786/FAST-RV.git
cd FAST-RV
pip install -r requirements.txt

Usage

import fast_rv

Example analysis is available in:

examples/51_peg.ipynb

FAST-RV currently assumes:

• single-planet systems
• a single instrument
• standard VizieR RV tables (time, RV, RV error)
