April Flowers for redOrbit.com - Your Universe Online Using the European Southern Observatory's (ESO) Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have observed what seems to be windy weather surrounding a T Tauri star—considered to be an infant analog of our own Sun. Such wind might explain why some T Tauri stars have disks that glow weirdly in infrared light while others have a more expected shine. The results of this study were published in a recent issue of the...

Donna McKinney, Naval Research Laboratory Dr. John Carr, a scientist at the U.S. Naval Research Laboratory (NRL), is part of an international team that has discovered what they believe is evidence of a planet forming around a star about 335 light years from Earth. This research is published in the August 20th issue of The Astrophysical Journal. Carr and the other research team members set out to study the protoplanetary disk around a star known as HD 100546, and as sometimes happens in...

protoplanetary discs in a double star

ESO Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found wildly misaligned planet-forming gas disks around the two young stars in the binary system HK Tauri. These new ALMA observations provide the clearest picture ever of protoplanetary disks in a double star. The new result also helps to explain why so many exoplanets — unlike the planets in the Solar System — came to have strange, eccentric or inclined orbits. The results will appear in the journal...

Complex Outflow Structure Revealed In The Binary UY Aurigae
2014-05-21 03:43:00

National Astronomical Observatory of Japan An international team of astronomers, led by Dr. Tae-Soo Pyo (Subaru Telescope, NAOJ), has revealed a complicated outflow structure in the binary UY Aur (Aurigae). The team observed the binary using the Gemini North"s NIFS (Near-Infrared Integral Field Spectrometer) with the Altair adaptive optics system. The team found that the primary star has a wide, open outflow, while the secondary star has a well-collimated jet. Because many stars form...

[ Watch the Video: ALMA Makes A Starry Cosmic Discovery ] redOrbit Staff & Wire Reports - Your Universe Online A team of Japanese astronomers has located evidence of a giant planetary system forming around a young star named HD142527, and their discovery could change existing theories on how planets form and provide new insights into the formation of a vast array of different planetary systems. Using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope, scientists...

John P. Millis, PhD for redOrbit.com - Your Universe Online Astronomers from the Strategic Exploration of Exoplanets and Disks with Subaru Telescope (SEEDS) project, an effort to search out other worlds, has turned its attention to a somewhat unusual source. Using the Subaru Telescope’s High Contrast Instrument for the Subaru Next Generation Adaptive Optics (HiCIAO), scientists were interested in a young star known as Ry Tau (Tauri) located some 460 light-years from Earth. Around this...

[ Listen to the Podcast: “How Planets Form” With Guest Dr. Eric Mamajek (Part 1): Your Universe Today Podcasts ] Lee Rannals for redOrbit.com - Your Universe Online The Subaru Telescope has helped astronomers capture the first vivid infrared image of a distant planet forming from a young star. Astronomers wrote in Astrophysical Journal Letters about an image of a curved arm of dust extending over a hole on a disk, which is a feature that could provide evidence that...

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Starting in early 2013, redOrbit will be launching a new podcast series called Your Universe Today, where we interview leading scientists about cutting-edge research in everything from space travel to the origins of our Universe. But we´re in the holiday spirit and couldn´t wait until January to unveil our new podcast project, so we´ve decided to give you a sneak peak of what´s to come. In...

Lee Rannals for redOrbit.com [ Watch the Video: The Birth of a Planet Simulation ] Planetary researchers have a new tool in their artillery when trying to hunt for extrasolar planets. Scientists can now use simulated models developed by a group of scientists of how planets are born, helping the hunt for extrasolar planets. Planets generally form when a molecular cloud collapses into a young star. As the leftover gas and dust form a disk around the star, the particulates inside...

Sweet! Distant Star Surrounded By Sugar

Watch the Video: Artist´s Impression of Glycolaldehyde Molecules | Watch the Video: Sugar Molecules Found in the Young Star Lee Rannals for redOrbit.com - Your Universe Online Most would assume that sugar is an essential part of life, but did you know it is actually considered a building block? Well, astronomers have now found these sweet organic molecules around a distant star. The finding reported in the Astrophysical Journal Letters proves that the building blocks of life...

Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...

Solar Nebula -- In astronomy, the solar nebula is the gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. In 1755 the German philosopher Immanuel Kant suggested that a nebula in slow rotation, gradually pulled together by its own gravitational force and flattened into a spinning disk, gave birth to the Sun and planets. A similar model, but with the planets being formed before the Sun, was proposed...
