Summary
| Description |
English: V1400 Centauri imaged by the Atacama Large Millimeter Array (ALMA) on 20 July 2017. This image was taken in Band 7, which covers a frequency range of 275-350 GHz or wavelength range of 0.8-1.1 mm. V1400 Centauri has moved slightly in the sky due to its proper motion, so the positions of V1400 Centauri in 2007 and 2017 are labeled and dash-circled in gray. The observed position of V1400 Centauri in the image is marked with the white cross. A scale bar for the angular distance is shown on the bottom left.
While V1400 Centauri itself was not detected by ALMA (due to the lack of warm dust surrounding the star), there is a faint object close to the star's location (labeled in yellow). This faint object could either be a background galaxy or a young substellar object surrounded by a disk of warm dust, which makes it a very likely candidate for J1407b, the object that eclipsed V1400 Centauri in 2007. The raw image filename in the ALMA Science Archive is "member.uid___A001_X87c_X409._1SWASP_J140747.93-394542.6__sci.spw17_19_21_23.cont.I.pbcor.fits". |
