Three Young Planets Around The K-dwarf K2-198: High-energy Environment, Evaporation History And ...

Planets orbiting young stars are thought to experience atmospheric evaporation as a result of the host stars’ high magnetic activity. We study the evaporation history and expected future of the three known transiting exoplanets in the young multiplanet system K2-198.

Based on spectroscopic and photometric measurements, we estimate an age of the K-dwarf host star between 200 and 500 Myr, and calculate the high-energy environment of these planets using eROSITA X-ray measurements.

SANTA CRUZ, CALIFORNIA "Dad, did you ever imagine that your formula would become so famous?" I ask the kind-eyed, 91-year-old person next to me on the patio. My dad, Frank Drake, is quiet for a moment. Perhaps he's thinking back to the November day 60 years ago when he unceremoniously drafted a formula that went on to shape humankind's hunt for extraterrestrial civilizations.

Studies of meteorites have found them to be surprisingly rich in water, suggesting that early in our planet's history 4.6 billion years ago, incoming asteroids delivered water and allowed Earth to become the h

UFO Hunting, With Harvard Data: Astrophysicist Advocates For Scientific Investigation

Avi Loeb: Two things. In 2017, there was an object — the first one that was identified from outside the solar system that arrived close to Earth — and it didn't look like anything we've seen before. It didn't look like a comet, it didn't behave like an asteroid. Loeb: Yes. And I thought maybe it's artificial in origin. And, in fact, I wrote a book about it, Extraterrestrial, that was published six months ago. And then a month ago, there was a report delivered to Congress saying: there are things in the sky above the U.S. whose nature is not identified.
