sidmon is a python program for receiving and recording submarine-transmitter signal intensities and directions in the VLF frequency range using a computer sound card. The intensities of these signals reflect the ability of radio waves at those wavelengths to propagate in what is essentially a waveguide formed by the earth and the ionosphere above it. Fluctuations in those signal intensities and directions often reflect daytime perturbations of the ionosphere by solar processes, such as solar flares and coronal mass ejections, making VLF receivers useful tools for probing the sun and the earth's ionosphere. For additional general information, see the web page at http://solar-center.stanford.edu/SID/.

This linux package is a VLF receiver for monitoring VLF transmitter signals for evidence of transients indicating ionospheric disturbances. It takes sample pairs from dual-channel sound cards and spectrally processes them to Stokes parameters.

Skydome and auch are tools for processing HAM Radio Astronomy. Captured radio signals can be analysed using *auch* and be plot on a skychart with the skydome program.

An astrophysical code to derive how extended is the water around protostars

Calculate Solunar Tables for any position on earth. Solunar tables are used to predict the best days and times of day to go hunting and fishing.

N-body program for astrophysical simulations

Cosmic ray electrons scatter on the photon fields around stars, including the sun, to create gamma rays by the inverse Compton effect. This program computes the spectrum and angular distribution of this emission. The software also includes general-purpose routines for inverse Compton scattering on a given electron spectrum, for example for interstellar or astrophysical source modelling. For further information see these publications: http://arxiv.org/abs/astro-ph/0607563, http://arxiv.org/abs/0801.2178, http://arxiv.org/abs/1104.2093, http://adsabs.harvard.edu/abs/2013NuPhS.239..266O and this conference presentation: https://confluence.slac.stanford.edu/download/attachments/130879399/poster_symposium_sun_2012.pdf and the corresponding conference paper http://arxiv.org/abs/1307.6798 2017 June 16: now available from gitlab https://gitlab.mpcdf.mpg.de/aws/stellarics which will be used for future develpments.

Tool for calculating Telescope specifications, Julian Date, Magnitude between two objects etc.

Universe@Home simulates the evolution of galaxies

UTS: Unified Telescope System. A modular system for controlling astronomical observatories.

WAFIMPA is the abbreviation of "WArped FIsh-eye Mirror Projection Adjuster". This is small GUI application. It helps to setup spheric mirror projection systems that frequently used in small planetariums (generates warp-map and mplayer ppm files).

This is a set of spectral models for use in the astronomical X-ray spectral modeling program XSPEC. The models calculate X-ray emission line Doppler profiles from the winds of OB stars.

Accrete is a physical simulation of solar system planet formation. This simulation works by modelling a dust cloud around a Sun-like star, injecting a series of masses which collect dust, and form planets by accretion.
