☆ Unusual world offers astronomers a glimpse into how planets become ‘hot Jupiters’
  + stars: | 2024-07-17 | by ( Ashley Strickland | ) edition.cnn.com   time to read: +9 min
The star is one of a binary pair, so the planet orbits the primary star, while the primary star orbits a secondary star. While Jupiter takes 4,000 Earth days to complete one orbit around the sun, hot Jupiters complete one orbit every few days. Astronomers use “eccentric” to refer to the shape of a planet’s orbit on a scale from zero to 1. “It’s a pretty extreme process in that the changes to the planet’s orbit are massive,” Millholland said. Discovering a second hot Jupiter precursor is helping astronomers to confirm the idea that high-mass gas giants transform into hot Jupiters as they migrate from eccentric to circular orbits, the researchers said.

☆ Puzzlingly massive planet found orbiting a small star
  + stars: | 2023-11-30 | by ( Ashley Strickland | ) edition.cnn.com   time to read: +5 min
The planet, about the mass of Neptune and more than 13 times as massive as Earth, was detected orbiting an ultracool M-dwarf star called LHS 3154 — which is nine times less massive than our sun. This graphic compares the sizes of our sun and Earth with the smaller, cooler LHS 3154 star and its orbiting planet, LHS 3154b. For example, small M dwarf stars are the most common throughout the Milky Way galaxy, and they typically have small, rocky planets orbiting them, rather than gas giant planets. “The planet-forming disk around the low-mass star LHS 3154 is not expected to have enough solid mass to make this planet,” Mahadevan said. A team of scientists led by Mahadevan built the HPF, which was designed to detect planets orbiting within the habitable zone of small, cool stars.

☆ Redefining retirement: How I quit my career to travel the world

A year later, we sailed her across the Channel to Calais, down rivers and canals to the south of France — an unforgettably wonderful experience. Then we fly south — like migrating geese — to spend yet another summer between Durban and Perth. The nomadic retirementNow meet South Africans Gail and Neil Greenfield, the epitome of retired nomads. Rather than slowing down, nomadic retirees quit work to travel the world. When it comes to the planning, big events like this year's Rugby World Cup in Japan are anchored in first, Gail explained.
