PDS 70
T Tauri-type star
PDS 70 (V1032 Centauri) is a very young T Tauri star in the constellation Centaurus. Located 370 light-years (110 parsecs) from Earth, it has a mass of 0.76 M☉ and is approximately 5.4 million years old. The star has a protoplanetary disk containing two nascent exoplanets, named PDS 70b and PDS 70c, which have been directly imaged by the European Southern Observatory's Very Large Telescope, as well as a third unconfirmed protoplanet. PDS 70b was the first confirmed protoplanet to be directly imaged.
Discovery and naming
The "PDS" in this star's name stands for Pico dos Dias Survey, a survey that looked for pre-main-sequence stars based on the star's infrared colors measured by the IRAS satellite.
PDS 70 was identified as a T Tauri variable star in 1992, from these infrared colors. PDS 70's brightness varies quasi-periodically with an amplitude of a few hundredths of a magnitude in visible light. Measurements of the star's period in the astronomical literature are inconsistent, ranging from 3.007 days to 5.1 or 5.6 days.
Protoplanetary disk
The protoplanetary disk around PDS 70 was first hypothesized in 1992 and fully imaged in 2006 with phase-mask coronagraph on the VLT. The disk has a radius of approximately 140 au. In 2012 a large gap (~65 au) in the disk was discovered, which was thought to be caused by planetary formation.
“PDS 70” enters the record as t Tauri-type star. Crown Archives preserves that source wording while asking what Tauri-type and star can confirm, complicate or overturn.
Why this record matters
“PDS 70” is worth following because a concise public description often conceals a longer documentary argument. Here, Tauri-type and star provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q55361304. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1992, 2006 and 2012.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
