astropy

26 4,210 9.9 Python

Astronomy and astrophysics core library

Project mention: Julia 1.10 Released | news.ycombinator.com | 2023-12-27

Astropy [0] lives at the heart of most work. It has a Python interface, often backed by Fortran and C++ extension modules. If you use Astropy, you're indirectly using libraries like ERFA [6] and cfitsio [7] which are in C/Fortran.
I personally end up doing a lot of work that uses the HEALPix sky tesselation, so I use healpy [2] as well.
Openorb is perhaps a good example of a pure-Fortran package that I use quite. frequently for orbit propagation [3].
In C, there's Rebound [4] (for N-body simulations) and ASSIST [5] (which extends Rebound to use JPL's pre-calculated positions of major perturbers, and expands the force model to account for general relativity).
There are many more, these are just ones that come to mind from frequent usage in the last few months.

RAnsac Assisted Spectral CALibration (by jveitchmichaelis)

Project mention: Ask HN: Show me your half baked project | news.ycombinator.com | 2023-10-12

Automated/template-free astronomical spectrograph/spectrometer calibration. Given an emission spectrum and a list of known wavelengths that you expect to see, we try and determine the pixel/wavelength relationship. Traditionally this would either be done with templates (convolve a known spectrum and see where it lines up) or by hand (identify peaks and pixels and shove them into Excel).

SolarGUI

6 4 0.0 Python

A GUI program which will contain information about solar system (any maybe other things).
StarScholar3D

3 0 9.0 Python

Dynamic 3D Visualisation of Stars Using The Yale Bright Star Catalogue in Python

Project mention: Exploring the Cosmos in 3D: StarScholar3D & StellarPhysicsHub Astronomy Projects | /r/Python | 2023-12-11

StellarPhysicsHub is a Flask-based web application designed for astronomy enthusiasts and researchers, offering an interactive platform to explore constellations and asterisms. The app uses Flask for backend development and SQLAlchemy for database interactions, backed by a SQLite database. It features a user-friendly interface with search functionality, dynamic content rendering using Jinja2, and employs StarScholar3D for interactive 3D visualisations. The responsive design ensures accessibility across devices however it is best viewed on a PC as the zoom functionality struggles with touch controls.
