Spectroscopy and chemical synthesis of interstellar ice analogues [PDF]

, 2014
Molecular synthesis and chemical evolution in the interstellar medium has been studied under laboratory conditions. The method of preparation and energetic processing of interstellar ice analogues on surfaces, spectroscopic principles for monitoring chemistry and morphology of these ice analogues and analysis methodologies are discussed in detail.

HDO Ice Detected toward an Isolated Low-mass Protostar with JWST

The Astrophysical Journal Letters
Water is detected in environments representing every stage of star and solar system formation, but its chemical evolution throughout these stages remains poorly constrained.

A Photometric System for Detection of Water and Methane Ices on Kuiper Belt Objects

, 2011
We present a new near-infrared photometric system for detection of water ice and methane ice in the solar system. The system consists of two medium-band filters in the K-band region of the near-infrared, which are sensitive to water ice and methane ice ...

Influence of ISPs from a polar sea-ice microalga on whipped cream detected by cryo-Raman microscopy [PDF]

, 2017
The occurrence of recrystallization and large ice areas after storage of frozen food products makes the use of ice-structuring proteins (ISPs) in food products meaningful.

JWST Spectrophotometry of the Small Satellites of Uranus and Neptune

The Planetary Science Journal
We use 1.4–4.6 μ m multiband photometry of the small inner Uranian and Neptunian satellites obtained with the James Webb Space Telescope’s near-infrared imager NIRCam to characterize their surface compositions.

V1647 Orionis: One Year into Quiescence

, 2007
We present new optical, near-IR, and mid-IR observations of the young eruptive variable star V1647 Orionis that went into outburst in late 2004 for approximately two years. Our observations were taken one year after the star had faded to its pre-outburst

Dissolved organic carbon loss from Yedoma permafrost amplified by ice wedge thaw

Environmental Research Letters, 2013
Pleistocene Yedoma permafrost contains nearly a third of all organic matter (OM) stored in circum-arctic permafrost and is characterized by the presence of massive ice wedges.
