We report on the discovery of a very prominent mid-infrared (18–25 μ m) excess associated with the trans-Neptunian dwarf planet (136472) Makemake. The excess, detected by the Mid-Infrared Instrument of the James Webb Space Telescope, along with previous ...

Our understanding of how exoplanets form and evolve relies on analyses of both the mineralogy of protoplanetary disks and their detailed structures; however, these key complementary aspects of disks are usually studied separately.

An Improved Atlas of Full-scan Spectra from ISO/SWS
We present an atlas of full-scan spectra from the Short-Wavelength Spectrometer (SWS) on board the Infrared Space Observatory after reprocessing and improving an earlier version published 22 yr ago. The SWS spectra cover the wavelength range from 2.35 to

Proto-Planetary Nebula with the Spitzer Space Telescope
The transition from Asymptotic Giant Branch star to Planetary Nebula is short-lived and mysterious. Though it lasts only a few thousand years, it is thought to be the time when the asymmetries observed in subsequent phases arise. During this epoch, the star is shrouded in thick clouds of dust and molecular gas; infrared observations are needed to ...

The Red Supergiant Progenitor of Type II Supernova 2024ggi
We present a detailed analysis of the progenitor and its local environment for the recently discovered Type II supernova (SN) 2024ggi at a distance of about 6.7 Mpc, by utilizing the pre-explosion images from the Hubble Space Telescope and Spitzer Space ...
