Limb-darkening effects on exoplanet transits
The effect of Stellar limb-darkening on transit light curves There are two main bodies involved in modeling a transit phenomenon: the star and the planet. We begin this educational journey by describing the stellar part of the transit model. Under Continue Reading
TESS-W Photometer
The TESS-W photometer allows us to share sky brightness data on the networkSTARS4ALL, but it is also a good complement to the astronomical observatory. With the standard version you have the sky brightness and the cloud estimate.Adding an anemometer and Continue Reading
M42 Orion Nebula
The Orion Nebula spans a 10º region in the sky, and contains interstellar clouds, star clusters, H II regions, and reflection nebulae. The nebula forms an almost spherical cloud, where the maximum density is reached near the central point. The Continue Reading
