🪐TOI-2195 A b is an inflated hot Neptune found orbiting an orange dwarf. Its extreme orbit and physical size suggest it was once a much larger gas giant that lost nearly 90 percent of its mass through gravitational interactions and intense tidal forces

Reflected light from the ultra-hot Neptune 🪐LTT 9779 b has been measured using high-resolution spectroscopy. The planet shows a high geometric albedo of 0.88, suggesting a highly reflective atmosphere likely dominated by clouds or scattering processes

Sub-Neptunes 🪐TOI-421 b and 🪐Gliese 3470 b show evidence of forming in water-poor regions. Modeling indicates that initial building blocks—rock, water, and soot—are the primary drivers of atmospheric diversity in these distant worlds

Three new hot Jupiters have been discovered orbiting stars nearing the end of their main sequence (⭐️TOI-3664,⭐️TOI-4034, ⭐️TOI-6564). All three planets have radii larger than Jupiter but lower masses

⭐️HD 81809 B shows a strange chemical composition compared to its primary star. A new study suggests this could be due to the star engulfing 25–75 Earth masses of planetary material
