We discuss our JHKLM photometry for nine carbon Mira stars, eighteen carbon semiregular variables, and two oxygen Mira stars. For fourteen carbon stars, we present and analyze their infrared light and color curves. For all of the observed objects, we have estimated the optical depths of the circumstellar dust envelopes, the angular diameters of the stars, and their temperatures.

IR photometry and models for the dust envelopes of two carbon stars
The results of JHKLM photometry of two carbon stars are presented: the irregular variable NQ Cas and the Mira star BD Vul. Data on the mean fluxes supplemented with mid-IR observations with the IRAS,…
IR photometry and dust-shell models for two carbon stars
We present JHKLM photometry of the carbon stars ST And and T Lyn acquired in 2000–2010. Along with brightness variations due to pulsations, changes on timescales of 2000–3000 days are also observed.…
IR photometry and a model of a dust shell in V2108 Ophiuchi
We present the results of JHKLM photometry of the oxygen Mira variable V2108 Oph acquired in 2000–2004. The period of brightness variations is refined (570 ± 3 days), and light and color curves in…
Infrared spectral variations of three Mira variable carbon stars with the 11.3 μm SiC feature
The spectral variations of three Mira variable carbon stars, V CrB, T Dra and V Cyg in the infrared are investigated based on ISO SWS data. It is found that either continua or molecular/dust features…
Near-infrared observations of the carbon stars TU Geminorum and SS Virginis at milliarcsecond resolution
Aims. High-angular resolution investigations of carbon stars. Methods. Milliarcsecond resolution observations in the near infrared K band by the method of lunar occultations are presented for the…
AGB variables and the Mira period–luminosity relation
Published data for large-amplitude asymptotic giant branch variables in the Large Magellanic Cloud (LMC) are re-analysed to establish the constants for an infrared (K) period-luminosity relation of…
Carbon-rich Mira variables: radial velocities and distances
Optical radial velocities have been measured for 38 C-type Mira variables (C-Miras). These data together with others in the literature are used to study the differences between optical and CO…
A Model of the Dust Envelope of the Carbon Mira Star V CrB from Photometry, Infrared Spectroscopy, and Speckle Polarimetry
Abstract $$UBVJHKLM$$ photometry for the carbon Mira star V CrB are presented. The infrared observations were carried out in the time interval 1989–2018, while the $$U$$ , $$B$$ , and $$V$$ data were…
The Radiative Pattern and Asymmetry of IRC +10216 at 11 μm Measured with Interferometry and Closure Phase
The unusual source IRC +10216 is the brightest stellar object at mid-infrared wavelengths in the northern hemisphere. Adding to its distinctiveness, the dust around IRC +10216 almost completely…

The effective temperatures of carbon-rich stars
We evaluate effective temperatures of 390 carbon-rich stars. The interstellar extinction on their lines of sights was determined and circumstellar contributions derived. The intrinsic (dereddened)…
Semiregular variables of types SRa and SRb. New JHKL'M-photometry for 200 stars
This paper presents new JHKL'M observations of 200 Semiregular variables (SRVs) of types SRa and SRb. The sample was defined in Kerschbaum & Hron (1992a, Paper I) by means of a certain limit in…
