Radvel_Introduction

Public repository for helping people to learn radvel

Example code for creating an anaconda environment that uses radvel:

conda create --name newrad python=3.6

conda activate newrad

conda install --channel "conda-forge" numpy

conda install scipy matplotlib cython astropy pandas

pip install corner celerite emcee

pip install radvel --upgrade

pip install h5py

------- Session 1. -------

1. Installation
2. Review Fulton et al. 2018
3. Introduction to RadVel, basic fit
   • Probably Pegasi 51b. An easy, large amplitude 1 planet fit, no trend, activity, etc.

---

------- Session 2. -------

1. Something a little more complicated. Let's try a multi-planet run, and let's include a system with some trend and curvature.
2. HD 191939 public data is probably a good choice for this

---

------- Session 3. -------

1. Let's get spicy. Let's do a fit that is hampered by activity, and requires a GP.
2. Kepler-21 is a good option, or possibly CoRoT-7

---

------- Session 4. -------

1. Advanced GP fits
   • Let's introduce the Chromatic GP Kernels from Cale et al. 2021. AU Mic should be our test case here.
2. More Advanced Radvel
   • Keplerdrive, modifying plots, decorrelation
