Aging Stars Dine on Their Planets: What Earth Can Learn from Red Giants
What the new findings reveal about aging stars Using NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have sharpened our understanding of how red giant stars—aged stars in a late evolutionary stage—interact with their planetary systems. The new results suggest these stellar elders are more destructive to nearby planets than previously believed. As a star exhausts…

Aging stars destroy their planets: What this means for Earth
Red giants and planetary doom: a clearer picture Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have sharpened our understanding of how aging stars—specifically red giants—interact with their orbiting planets. As stars exhaust their nuclear fuel, they swell into red giants, their outer layers puffing up and reaching farther into the surrounding planetary system. Recent…

Aging Stars May Be Devastating for Planets: Could Earth Be Next?
Stars Grow Stronger, Worlds Get Destroyed: The Red Giant Challenge Astronomers have long known that stars evolve, expanding dramatically as they exhaust their nuclear fuel. Now, using NASA’s Transiting Exoplanet Survey Satellite (TESS), researchers have shown that aging stars in the red giant phase are more destructive to their orbiting planets than previously believed. This…

Transiting Planets in Binaries II: A Dichotomy in Orbital Alignment of Small Planets in Close Binary Systems
Introduction Stellar multiplicity has long been recognized as a key factor shaping how planets form and evolve. Building on a survey of nearby systems, this study focuses on transiting planets found in binary hosts and leverages significant Hipparcos-Gaia astrometric accelerations to identify and characterize companions. In particular, we examine 54 TESS Objects of Interest (TOIs)…
