First laboratory and on-sky results of an adaptive secondary mirror with TNO-style actuators on the NASA Infrared Telescope Facility
Ellen Lee, Mark Chun, Olivier Lai +14
We are developing an adaptive secondary mirror (ASM) that uses a new actuator technology created by the Netherlands Organization for Applied Scientific Research (TNO). The TNO hybr…
SpeX near-infrared spectroscopic extinction curves in the Milky Way
Marjorie Decleir, Karl D. Gordon, Jennifer E. Andrews +7
Interstellar dust extinction curves provide valuable information about dust properties, including the composition and size of the dust grains, and are essential to correct observat…
V4046 Sgr: Touchstone to Investigate Spectral Type Discrepancies for Pre-main Sequence Stars
Joel H. Kastner, Valerie Rapson, Benjamin Sargent +2
Determinations of the fundamental properties (e.g., masses and ages) of late-type, pre-main sequence (pre-MS) stars are complicated by the potential for significant discrepancies b…
Near-Discovery Observations of Interstellar Comet 3I/ATLAS with the NASA Infrared Telescope Facility
Theodore Kareta, Chansey Champagne, Lucas McClure +8
Interstellar Objects are comets and asteroids that formed around other stars but were ejected before they could accrete into exoplanets. They therefore represent a rare opportunity…
PTF10nvg: An Outbursting Class I Protostar in the Pelican/North American Nebula
Kevin R. Covey, Lynne A. Hillenbrand, Adam A. Miller +28
During a synoptic survey of the North American Nebula region, the Palomar Transient Factory (PTF) detected an optical outburst (dubbed PTF10nvg) associated with the previously unst…
Facility integration of the NASA IRTF adaptive secondary mirror
Ellen Lee, Mark Chun, Michael Connelley +12
IRTF-ASM-1 has been functioning well since its first light in 2024. This adaptive secondary mirror (ASM) was primarily developed to be an on-sky demonstration of the new hybrid var…
