The Satellite of Procyon [PDF]

Nature, 1889
IT is well-known that Procyon, like Sirius, does not travel through space in a straight line, its motion undergoing changes similar to those which would result from the disturbing action of a large satellite. This explanation was advanced by Bessel in 1844, and though the satellite has not yet been seen, its existence has been placed beyond reasonable ...

The Pulsation Properties of Procyon A [PDF]

The Astrophysical Journal, 1999
A grid of stellar evolution models for Procyon A has been calculated. These models include the best physics available to us (including the latest opacities and equation of state) and are based on the revised astrometric mass of Girard et al (1996 ...

Oscillations on the star Procyon [PDF]

Nature, 2004
Stars are sphere of hot gas whose interiors transmit acoustic waves very efficiently. Geologists learn about the interior structure of Earth by monitoring how seismic waves propagate through it and, in a similar way, the interior of a star can be probed ...

Seismology of Procyon A: determination of mode frequencies, amplitudes, lifetimes, and granulation noise [PDF]

, 2006
The F5 IV-V star Procyon A (aCMi) was observed in January 2001 by means of the high resolution spectrograph SARG operating with the TNG 3.5m Italian telescope (Telescopio Nazionale Galileo) at Canary Islands, exploiting the iodine cell technique.

The non-detection of oscillations in Procyon by MOST: is it really a surprise? [PDF]

, 2005
We argue that the non-detection of oscillations in Procyon by the MOST satellite reported by Matthews et al. (2004) is fully consistent with published ground-based velocity observations of this star.

A Search for Exozodiacal Dust and Faint Companions Near Sirius, Procyon, and Altair with the NICMOS Coronagraph [PDF]

, 2000
We observed Sirius, Altair, and Procyon with the NICMOS Coronagraph on the Hubble Space Telescope to look for scattered light from exozodiacal dust and faint companions within 10 AU from these stars. We did not achieve enough dynamic range to surpass the

Ectoparasitic Arthropods Collected From Some Northern Ohio Mammals [PDF]

, 2017
Ectoparasitic arthropods were collected from some fur-bearing mammals in northern Ohio. Specimens representing seven mammalian species were examined and found to collectively harbor acarines, fleas, and biting lice.

EFFECT OF RACCOON (PROCYON LOTOR) REDUCTION ON BLANDING’S TURTLE (EMYDOIDEA BLANDINGII) NEST SUCCESS [PDF]

, 2016
The Lake County Forest Preserve District has monitored a state-endangered Blanding’s Turtle (Emydoidea blandingii) population at two adjoining nature preserves along the Illinois–Wisconsin border since 2004.

Hubble Space Telescope Astrometry of the Procyon System

, 2015
The nearby star Procyon is a visual binary containing the F5 IV-V subgiant Procyon A, orbited in a 40.84 yr period by the faint DQZ white dwarf Procyon B. Using images obtained over two decades with the Hubble Space Telescope, and historical measurements

Asteroseismology of the Hyades red giant and planet host epsilon Tauri [PDF]

, 2019
Asteroseismic analysis of solar-like stars allows us to determine physical parameters such as stellar mass, with a higher precision compared to most other methods.
