Long-term (1984–2008) JHKLM photometry for 254 objects is presented. The observations were carried out in the standard JHKLM photometric system using an original method and a modern IR photometer designed and built at the Sternberg Astronomical Institute. Our program of studies included searches for and studies of relatively hot circumstellar dust envelopes. The most important results obtained using these observations include the following. We have detected relatively hot dust envelopes in a… 
Dust around the Cool Component of D-Type Symbiotic Binaries
D type symbiotic binaries are an excellent astrophysical laboratory for investigation of the dust properties and dust formation under the influence of theMira stellar wind and nova activity and of
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 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,
FG SGE: Evolution of the circumstellar dust shell (JHKLM Photometry in 1985–2013)
Long-term (1985–2013) JHKLM photometry for FG Sge is analyzed. Parameters of the supergiant and optical properties of the dust in the dust shell (DS) have been refined. Given the optical photometry,
IR photometry and models for the dust shells of two oxygen Mira variables
Long-term JHKLM photometric measurements of the oxygen Mira variables RU Her and RS Vir are presented. Variations of the brightnesses and colors of these stars over the observation period are
HST Images Reveal Dramatic Changes in the Core of IRC+10216
IRC+10216 is the nearest carbon star with a very high mass-loss rate. The existence of a binary companion has been hinted at by indirect observational evidence, such as the bipolar morphology of its
The Evolving Radio Photospheres of Long-period Variable Stars
Observations with the Karl G. Jansky Very Large Array at 46 GHz (λ ≈ 7 mm) have been used to measure the size and shape of the radio photospheres of four long-period variable stars: R Leonis (R Leo),
The weather report from IRC+10216: evolving irregular clouds envelop carbon star
High angular resolution images of IRC+10216 are presented in several near infrared wavelengths spanning more than 8 years. These maps have been reconstructed from interferometric observations
NGC 2392 is a young double-shell planetary nebula (PN). Its intrinsic structure and shaping mechanism are still not fully understood. In this paper we present new spectroscopic observations of NGC
Dynamics of wind and the dusty environments in the accreting T Tauri stars RY Tauri and SU Aurigae
Classical T Tauri stars with ages of less than 10 Myr possess accretion discs. Magnetohydrodynamic processes at the boundary between the disc and the stellar magnetosphere control the accretion and


The majority of symbiotic and VV Cephei stars have near infrared continua closely resembling those of late-type stars. Evidence for weak infrared excesses has been found in the three stars RY Sct, W
UBVRI-JHKL photometric catalogue of symbiotic stars.
The results of an optical and infrared photometric survey of a large sample of symbiotic stars, 93 objects out of the approximately 150 known class members, are presented. A sample of 78, mostly
What are Pulsating Stars?
The detection by the Kitt Peak and Lick Observatories of optical pulsations from CP 1919 came when astronomers were beginning to suspect that the pulsations were only in the radio spectrum, and theoretical interpretation of the pulsed radio signals has barely kept pace with the flow of new measurements.
Erratum: Self-similarity and scaling behaviour of infrared emission from radiatively heated dust — I. Theory
Dust infrared emission possesses scaling properties. Overall luminosity is never an input parameter of the radiative transfer problem, spectral shape is the only relevant property of the heating
Near Infra-Red Magnitudes of 248 Early-Type Emission-Line Stars and Related Objects
Nearly 250 early-type emission-line stars have been observed in the near infrared; approximately two thirds of these are found to exhibit excess radiation at these wavelengths. Two distinct
