Discovery of an Extremely r-process-enhanced Thin-disk Star with [Eu/H] = +0.78 Journal: The Astrophysical Journal Letters Published: 2024-07-24 DOI: 10.3847/2041-8213/ad5ffd Affiliations: 7 ...

Disk galaxies, like our own Milky Way galaxy, commonly consist of both a thick and thin disk of stars—each with different features, including stellar population and movement. Three major ...

"To see thin stellar disks already in place 8 billion years ago, or even earlier, was surprising." Some of the edge-on thin disk and thick disk galaxies studied by the JWST.

Most of the stars in the thin disk host at least one planet, astronomers think. Observations show that nearly half have a planet whose size is between Earth’s and Neptune’s.

High-mass, single-disk galaxies transformed into dual-disk structures by forming an embedded thin disk around 8 billion years ago in our approximately 14-billion-year-old universe.

Comet 31/ATLAS is only the third interstellar object to ever be observed whizzing through the Solar System. While its origins ...

"This is the first time it has been possible to resolve thin stellar disks at higher redshift. What's really novel is uncovering when thin stellar disks start to emerge," Emily Wisnioski, study ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their ...

A high-power ytterbium thin-disk laser drives an optical parametric oscillator (OPO) to generate high-power, stable pulses in the short-wave infrared (SWIR) spectral range.

"These ancient stars in the disc suggest that the formation of the Milky Way's thin disc began much earlier than previously believed, by about 4-5 billion years," study lead author Samir Nepal, a ...
