How to find exoplanets and ‘listen’ to their stars with TESS
Today’s post investigates how multitasking TESS is not only detecting exoplanets, but ‘listening’ to their stars, allowing us to find out more about both planet and star.
What is causing these Little Dippers?
Could exocomets be causing these strange shaped lightcurves?
How Many Planets Will We Find Around White Dwarfs?
We know that white dwarfs have planets, but there are very few that we have detected directly. An upcoming survey may change that.
Can we predict if planets are lonely?
Can the properties of a known planet system predict if that system has additional undetected planets?
A very close planet that is way out of line
Transiting exoplanets generally orbit in the same plane, so how is this planet so misaligned in this multi-planet system?
Deflating a Planet: Helium Loss in the Atmosphere of Wasp-107b
It has long been theorized that exoplanet atmospheres should be partially composed of helium — now we finally have our first detection in the atmosphere of Wasp-107b. Today’s bite explains how the authors observed helium and discuss what this means for the atmosphere of this planet.
