Continuing on the thread from Friday’s post, I also attended the recent SPIE meeting. Here are my thoughts, as someone who is on the science side of the field, on the engineering and instrumentation conference.
Radio observations of the diffracted shadow cast by an asteroid can be used to nail down its location and determine its size and shape.
Statistical confirmation of long-period, low SNR candidates should be taken with a grain of salt. The reliability is too low to confirm individual systems without followup observations and the 99% confidence validation of Kepler-452b is likely closer to 90%.
Using 14 years of high resolution near-infrared imaging, radio observations of molecular gas, and a hydrodynamic simulation the authors show that spiral arms seen in the protoplanetary disk around HD 100453 A are caused by its M-dwarf companion.
HIP 65426 b is the first planet discovered with the SPHERE imager on the VLT. It is an intriguing planet for future study of cloud formation but how did it form in the first place?
