Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of researchers has detected formic acid in the circumstellar disk of the TW Hydrae system. It is the first discovery of the simplest carboxylic ...
A team using the Hubble Space Telescope has imaged circumstellar disk structures (CDSs) around three stars similar to the sun. The stars are all G-type solar analogs, and the disks themselves share similarities with our Solar ...
