Photometry & spectrophotometry of the Herbig Ae star RR Tauri

DOI: 10.48550/arXiv.1808.01645 Bibcode: 2019JBAA..129..216B

Boyd, D.

Multicolour broadband photometry and flux-calibrated low-resolution spectroscopy, obtained between 2014 & 2018, are used to investigate the behaviour of the highly variable Herbig Ae star RR Tauri.

Solar Irradiance Variability, Influenced by r Modes

DOI: 10.3847/1538-4357/aaee80 Bibcode: 2019ApJ...870...20W

Wolff, Charles L.

A spectrum of the four-decade solar irradiance record has a prominent cluster of power for periodicities near 1 yr. Correlating irradiance with a bandpass filter showed that periodicity values were not constant, but varied sinusoidally with each cycle lasting 14 ± 1 yr. The large modulation amplitude makes solar frequencies ≥1 yr^-1 hard…

Comparing photometric and trigonometric distance scales in the Galaxy with Gaia DR2

DOI: 10.26087/INASAN.2019.3.1.050 Bibcode: 2019INASR...3..317K

Kovaleva, D. A.; Piskunov, A. E.; Kharchenko, N. V.

The average trigonometric parallaxes, determined according to Gaia DR2 for 143 open clusters at distances up to 8.5 kpc, are compared with the distances to the same clusters, determined in the framework of the MWSC project by the method of isochrone fitting. It is shown that the agreement between the trigonometric and photometric distance scales f…

Hints of the Existence of C-rich Massive Evolved Stars

DOI: 10.3847/1538-4357/ab133e Bibcode: 2019ApJ...876..116Q

Cernicharo, José; Agúndez, Marcelino; Quintana-Lacaci, Guillermo +6 more

We aim to study the properties of a particular type of evolved stars, C-rich evolved stars with high expansion velocities. For this purpose we have focused on the two best studied objects within this group, IRC+10401 and AFGL 2233. We focused on determining their luminosity by studying their spectral energy distribution. Also, we have obtained sin…

Improvement of Simplified Models of Variability of Stars: A review

DOI: 10.48550/arXiv.1902.00963 Bibcode: 2019OEJV..197...28A

Andronov, I. L.

Astronomical data are typically irregular in time, e.g. the space (HIPPARCOS/TYCHO, KEPLER, GAIA, WISE etc.) and ground-based CCD (NSVS, ASAS, CRTS, SuperWASP etc.) and photographic (Harvard, Sonneberg, Odessa etc.) photometrical surveys. This leads to cancellation of the conditions, which lead to the orthogonality of the basic functions, and thus…

Long-term spectroscopic survey of T Tauri stars in the Taurus-Auriga star-forming region

Bibcode: 2019CoSka..49..363P

Kundra, E.; Budaj, J.; Guenther, E. +5 more

Long-term spectroscopic monitoring of 22 T Tauri stars located in the Taurus-Auriga star-forming region (SFR) is presented. The medium and high-dispersion spectra were obtained at the Stará Lesná (SLO), Skalnaté Pleso (SPO) and Tautenburg observatory (TLS) during 2015—2018. The broadening function technique was used to determine the radial and pro…
