Autor: Samuel A. Beiler, Michael C. Cushing, J. Davy Kirkpatrick, Adam C. Schneider, Sagnick Mukherjee, Mark S. Marley, Federico Marocco, Richard L. Smart

Publikováno v: The Astrophysical Journal, Vol 973, Iss 2, p 107 (2024)

We present infrared spectral energy distributions of 23 late-type T and Y dwarfs obtained with the James Webb Space Telescope. The spectral energy distributions consist of NIRSpec PRISM and MIRI low-resolution spectrometer spectra covering the ∼1�

In November 2019, the nearby single, isolated DQ-type white dwarf LAWD 37 (WD 1142-645) aligned closely with a distant background source and caused an astrometric microlensing event. Leveraging astrometry from \Gaia{} and followup data from the \text

Publikováno v: Monthly Notices of the Royal Astronomical Society. 510:2597-2616

The Gaia early Data Release 3 has delivered exquisite astrometric data for 1.47 billion sources, which is revolutionizing many fields in astronomy. For a small fraction of these sources, the astrometric solutions are poor, and the reported values and
