We present observations of the young stars TW Hya and HD 100546 made with the Australia Telescope Compact Array at 89 GHz with ~2'' resolution and ~3 mJy continuum sensitivity. Compact thermal dust continuum emission is detected from disks surrounding both stars. HD 100546 also shows hints of extended emission, presumably a residual protostellar envelope, which is also visible in scattered light at optical wavelengths. For TW Hya, HCO+ J = 1-0 line emission from the circumstellar disk is…

VLA Imaging of the Disk Surrounding the Nearby Young Star TW Hydrae.
TLDR
The TW Hydrae system is perhaps the closest analog to the early solar nebula and the estimates of mass and mass accretion rates are uncertain since the gas-to-dust ratio in the TW Hya disk may have evolved from the standard interstellar value.
Infrared Views of the TW Hydra Disk
The face-on disk around TW Hya is imaged in scattered light at 1.1 and 1.6 km using the coronagraph in the Near Infrared Camera and Multi Object Spectrometer aboard the Hubble Space Telescope.

We have developed a physically self-consistent model of the disk around the nearby 10 Myr old star TW Hya that matches the observed spectral energy distribution and 7 mm images of the disk. The model

We derive hydrostatic, radiative equilibrium models for passive disks surrounding T Tauri stars. Each disk is encased by an optically thin layer of superheated dust grains. This layer reemits

X-ray and molecular emission from the nearest region of recent star formation.
TLDR
Being at least three times closer to Earth than any well-studied region of star formation, the TW Hya Association serves as a test-bed for the study of x-ray emission from young stars and the formation of planetary systems around sunlike stars.
