  • Binary Star PDS 144B in Scorpius has a Proplyd – Ionized Protoplanetary Disk

    PDS 144B is part of a binary star system known as PDS 144, which is notable for being the first confirmed Herbig Ae/Be binary system (2012) where both stars drive jets. Herbig Ae/Be stars are a class of pre-main-sequence stars that are more massive than T Tauri stars and are characterized by their emission lines…

  • Dimethyl Ether Detected in MWC 480 Protoplanetary Disk

    Dimethy Ether was first synthesised in 1835. It is expected to be used in biofuels in the future. The MWC 480 protoplanetary disk is a subject of significant interest due to its complex structure and potential insights into planet formation processes. Star Characteristics Protoplanetary Disk Features Kinematic and Chemical Properties Overall, the MWC 480 protoplanetary disk…

  • HH 48 NE Protoplanetary Disk Ices at High Disk Altitudes

    “To explain the presence of ices at high disk altitudes, we propose two possible scenarios: a disk wind that entrains sufficient amounts of dust, thus blocking part of the stellar UV radiation, or vertical mixing that cycles enough ices into the upper disk layers to balance ice photodesorption.” HH 48 NE is a protostar located…

  • Protoplanetary Disk Instability Around AB Aurigae (AB Aur)

    Overview AB Aurigae, commonly referred to as AB Aur, is a young star located in the constellation Auriga. It is a Herbig Ae/Be star, which means it is a pre-main-sequence star still in the process of formation. It has a stellar classification of A0Ve, matching an A-type main-sequence star with emission lines in the spectrum.…

  • Formalhaut A with First Asteroid Belt Seen Outside Solar System

    Fomalhaut A is a bright star and was known to the Persian and Arabic Astronomers. The name of the star is Arabic and means “mouth of the fish”. It belongs to a Tripple Star System 25 light-years away from earth. Formalhaut A has several notable characteristics: Fomalhaut Dusty Debris Disk (MIRI Image), James Webb Telescope…

  • HL Tau Protoplanetary Disk Contains More Water Than Earth

    The observations show that there is at least three times more water in the inner disc of the young Sun-like star HL Tauri than in all of Earth’s oceans combined. HL Tau also called HL Tauri is a young T Tauri star located approximately 450 light-years away from earth in the Taurus Molecular Cloud. It…

  • Infant Star SAO 206462 With Protoplanetary Disk 440 Lightyears From Earth

    SAO 206462 (also known as HD 135344B) is a young Herbig F star in the constellation Lupus with a prominent circumstellar protoplanetary disk. The Subaru Telescope captured remarkable images of this system, revealing never-before-seen details of a solar system in the making: 4. Recent high-resolution observations from the James Webb Space Telescope have captured detailed…
