Can the properties of a known planet system predict if that system has additional undetected planets?
Transiting exoplanets generally orbit in the same plane, so how is this planet so misaligned in this multi-planet system?
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.
With the launch of TESS, we will soon have many more exoplanet candidates. But how do we determine which are the most valuable for follow-up observations?
NASA’s TESS spacecraft has launched! Today’s paper predicts how many exoplanets it will find.
Statistical confirmation of long-period, low SNR candidates should be taken with a grain of salt. The reliability is too low to confirm individual systems without followup observations and the 99% confidence validation of Kepler-452b is likely closer to 90%.
