The First Extrasolar Planet Discovered with a New Generation High Throughput Doppler Instrument
Jian Ge, Julian van Eyken, Suvrath Mahadevan +17
We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new generation Doppler instrument. The planet orbits HD 102195, a you…
High Contrast Imaging with Gaussian Aperture Pupil Masks (GAPMs)
J. H. Debes, J. Ge
Gaussian aperture pupil masks (GAPMs) can in theory achieve the contrast requisite for directly imaging an extrasolar planet around a nearby solar type star. We outline the process…
Detections of the 2175 ÅDust Feature at 1.4z 1.5 from the Sloan Digital Sky Survey
Junfeng Wang, Patrick B. Hall, Jian Ge +2
The strongest spectroscopic dust extinction feature in the Milky Way, the broad absorption bump at 2175 Å, is generally believed to be caused by aromatic carbonaceous materials --…
Evidence of Planetesimal infall on to the very young Herbig Be star LkH234
Abhijit Chakraborty, Jian Ge, Suvrath Mahadevan
We report here the first evidence for planetesimal infall onto the very young Herbig Be star LkH234. These results are based on observations acquired over 31 days using spectro…
Using Notch-Filter Masks for High Contrast Imaging of Extrasolar Planets
J. H. Debes, J. Ge, M. J. Kuchner +1
We present the first laboratory experiments using a notch-filter mask, a coronagraphic image mask that can produce infinite dynamic range in an ideal Lyot coronagraph according to…
Unveiling Su Aurigae in the near Infrared: New high spatial resolution results using Adaptive Optics
Abhijit Chakraborty, Jian Ge
We present here new results on circumstellar nebulosity around SU Aurigae, a T-Tauri star of about 2 solar mass and 5 Myrs old at 152 pc in the J, H and K bands using high resoluti…
