Description
Nine type I post-main-sequence nebulae were observed in CO J = 2-1 using the NRAO 12-m antenna at Kitt Peak. It is found that, at the most, 20 percent of type I sources have antenna temperatures of greater than 0.2 K. The results suggest secondary kinematic splitting of the primary emission shell, and confirm the presence of high velocity outflows distinguished by an anomalous spatiokinematic morphology.

    Characterisation at Cryogenic Temperatures of an Attenuator for an Application of Astrophysical Instrumentation with MKIDs
    The use of non-cryogenic certified commercial electronics for cryogenic applications may be attractive due to their cost and availability, but it also carries risks related to reliability, performance and thermal compatibility. The decision to use commercial components that are not certified for cryogenics instead of components specifically

    Blue supergiants as a progenitor of intermediate-luminosity red transients
    The current perspective about the explosions of massive hydrogen-rich blue supergiants is that they resemble SN 1987A. These so-called peculiar Type II supernovae, however, are one of the rarest types of supernovae and may not hence be the fate of all blue supergiants. In this work, we explore other explosion scenarios for blue supergiants. We
