| Abstract | This program will measure the high-energy flux from TOI-2096, a nearby M dwarfhosting two small planets (1.6 and 2.1 Earth radii) near a mean-motion resonancestraddling the stars habitable zone. TOI-2096 is active and flares frequently,making it an ideal test case for exploring how the increased activity of M dwarfhosts can drive atmospheric mass loss for small planets. We are currentlyconducting a ground-based campaign to measure the planet masses and bulkdensities using transit timing variations. We also require a measurement of thehigh energy flux of the host star to characterize the corresponding mass losshistories of the two planets. This system will provide an invaluable benchmarkfor population-level studies of small planets orbiting active M dwarfs. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
