Physicists Observe Oxygen-28 for First Time

Aug 31, 2023 by Enrico de Lazaro

The oxygen-28 (28O) nucleus is of particular interest as, with the Z = 8 (protons) and N = 20 (neutrons) magic numbers, it is expected in the standard...

ALMA Detects Fluorine in Distant Star-Forming Galaxy

Nov 8, 2021 by News Staff

Fluorine is one of the most interesting elements for nuclear and stellar astrophysics. Fluorine abundance was first measured for stars other than the Sun...

New Exotic Isotope of Fluorine Discovered: Fluorine-13

Apr 5, 2021 by Enrico de Lazaro

A team of U.S. physicists has created a new isotope of fluorine, fluorine-13 (13F), via a charge-exchange reaction between a beam of oxygen-13 (13O) and...

A research team led by Northwestern University scientists has uncovered the structural makeup of human dental enamel at unprecedented atomic resolution,...

An artist’s impression of the collision of two stars, like the ones that formed CK Vulpeculae. The inset illustrates the inner structure of one red giant before the merger. A thin layer of 26Al (brown) surrounds a helium core. An extended convective envelope (not to scale), which forms the outermost layer of the star, can mix material from inside the star to the surface, but it never reaches deep enough to dredge 26Al up to the surface. Only a collision with another star can disperse 26Al. Image credit: NRAO / AUI / NSF / S. Dagnello.

Radioactive Molecule Found in Stellar Merger Remnant

Aug 2, 2018 by News Staff

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Northern Extended Millimeter Array (NOEMA) have made the first definitive...

This image shows a pellet of plutonium-238 dioxide. The pellet is glowing red because of the heat generated by the radioactive decay (primarily alpha) of the fuel. Such pellets were used in radioisotope thermoelectric generators that powered NASA’s Galilleo and Cassini spacecraft on missions to Jupiter and Saturn, respectively.
