![]() ![]() Water in the terrestrial planet-forming zone of the PDS 70 disk. Most likely, surrounding material such as dust and other water molecules serves as a protective shield.Īs a result, the water detected in the inner disk of PDS 70 could survive destruction. Such a transport system would be surprising, since the dust would have to cross the large gap carved out by the two giant planets, PDS 70b and PDS 70c.Īnother question raised by the discovery is how water could survive so close to the star, when the star’s ultraviolet light should break apart any water molecules. One possibility is that water molecules are forming in place, where we detect them, as hydrogen and oxygen atoms combine.Ī second possibility is that ice-coated dust particles are being transported from the cool outer disk to the hot inner disk, where the water ice sublimates and turns into vapor. Waters and colleagues considered two different scenarios to explain their finding. The discovery raises the question of where the water came from.ĭr. “Combined with our detection of water vapor, the inner disk is a very exciting place.” “We find a relatively high amount of small dust grains,” said Radboud University astronomer Rens Waters, co-author of a study published in the journal Nature. ![]() However, they do see the raw materials for building rocky worlds in the form of silicates. The outer planet, PDS 70c, is located near the outer edge of the disk gap at 34 AU from the star, similar to Neptune’s distance from our Sun.Īstronomers haven’t yet detected any planets forming within the inner disk of PDS 70. The inner planet, PDS 70b, is located within the disk gap at a distance of about 22 AU from the star, similar to the orbit of Uranus in our Solar System. PDS 70 hosts two protoplanets and a huge circumstellar disk of dust and gas in which a large region from 20 to 40 AU is cleared of dust. PDS 70 is a K7-type star located 370 light-years away from Earth in the constellation of Centaurus.Īlso known as V* V1032 Cen and IRAS 14050-4109, this star is cooler than our Sun and is estimated to be 5.4 million years old. Stream live to Matlab or via TCP/IP protocol (listener CURRY, Matlab, custom software), suitable for Brain Computer Interface (BCI) and related applications. CURRY 8 data files are fully compatible with EEGLAB.This artist’s concept portrays PDS 70 and its inner protoplanetary disk. Each amplifier has its own set-up image to ensure ease of use in setting the system. Acquisition in CURRY is enhanced with easier, more flexible, and more advanced tools for on-line data processing, with up to 512 channels and sampling rates up to 20 kHz.ĬURRY supports EEG data acquisition with SynAmps 2/RT, Siesta, NuAmps, Neuvo, Grael, and E-Series amplifiers. The Acquire and Online Signal Processing package consists of all primary features and functions needed for acquiring high-quality EEG/EP/ERP data and online/real-time processing. The CURRY Neuroimaging Suite software is divided into several modules that can stand alone or work together to maximize your lab’s flexibility.

Using the TCP/IP interface, data is immediately available to other packages (for instance Matlab) and allows for BCI applications. All the features required for data acquisition are supported for instance impedance check, online filtering, real-time event averaging, real-time fMRI/TMS artefact correction and many more. The CURRY 8 X Data Acquisition package is an easy-to-use and reliable tool for EEG data recording and online processing. ![]()
