1.1. Interstellar Clouds and Interstellar Chemistry A space between stars is not completely a
vacuum, but is filled up with interstellar gas, whose average number density of H nuclei in all …

We present an overview of the Large Program," Early Planet Formation in Embedded Disks
(eDisk)," conducted with the Atacama Large Millimeter/submillimeter Array (ALMA). The …

We present a grid of radiation transfer models of axisymmetric young stellar objects (YSOs),
covering a wide range of stellar masses (from 0.1 to 50 M☉) and evolutionary stages (from …

We present two-dimensional radiation transfer models of class I protostars and show the
effect of including more realistic geometries on the resulting spectral energy distributions …

We present model spectral energy distributions (SEDs), colors, polarization, and images for
an evolutionary sequence of a low-mass protostar from the early collapse stage (Class 0) to …

This paper presents a large spectral line and continuum survey of eight deeply embedded,
low-mass protostellar cores using the SMA. High-excitation line emission from 11 molecular …

We have investigated the protostellar disk around a Class 0/I protostar, L1527 IRS, using
multiwavelength observations of the dust continuum emission at λ= 0.87, 2.1, 3.3, and 6.8 …

We have detected the high-excitation lines of carbon-chain molecules such as C 4 H 2 (J=
10_ {0, 10}{\mbox {--}} 9_ {0, 9}), C 4 H (N= 9 {\mbox {--}} 8, F 1, F 2), lC 3 H 2 (4 1, 3-3 1, 2) …

Aperture synthesis observations of HCO+ J= 1–0, 13 CO 1–0, and C 18 O 1–0 obtained with
the Owens Valley Millimeter Array are used to probe the small-scale (5 &arcsec; ≈ 700 …

Studying the physical and chemical conditions of young embedded disks is crucial to
constrain the initial conditions for planet formation. Here we present Atacama Large …
