Digital quantum computers provide a computational framework for solving the Schrödinger
equation for a variety of many‐particle systems. Quantum computing algorithms for the …

A multitude of phenomena—such as the chemical enrichment of the Universe, the mass
spectrum of planetary nebulae, white dwarfs and gravitational wave progenitors, the …

To date, 204 individual molecular species, comprised of 16 different elements, have been
detected in the interstellar and circumstellar medium by astronomical observations. These …

To date, 241 individual molecular species, composed of 19 different elements, have been
detected in the interstellar and circumstellar medium by astronomical observations. These …

We found four series of harmonically related lines in IRC+ 10216 with the Yebes 40 m and
IRAM 30 m telescopes. The first series corresponds to a molecule with a rotational constant …

We report the detection of the sulfur-bearing species NCS, HCCS, H 2 CCS, H 2 CCCS, and
C 4 S for the first time in space. These molecules were found towards TMC-1 through the …

Chemical equilibrium has proven extremely useful for predicting the chemical composition of
AGB atmospheres. Here we use a recently developed code and an updated thermochemical …

Context. Detailed astrochemical models are a key component to interpret the observations of
interstellar and circumstellar molecules since they allow important physical properties of the …

We report on the detection of two series of harmonically related doublets in IRC+ 10216.
From the observed frequencies, the rotational constant of the first series is B= 1380.888 MHz …

We report on the detection of a series of six lines in the ultra-deep Q-band integration
towards IRC+ 10216 carried out with the Yebes 40 m telescope, which are in harmonic …
