Spectral study of V565 Mon: probable FU Ori-like or chemically peculiar star

نویسندگان

چکیده

We present the detailed spectroscopic study of V565 Mon pre-main-sequence star, which is illuminating star Parsamian 17 cometary nebula. Observations were performed with 2.6 m telescope in Byurakan Astrophysical Observatory 15 February 2018. Radial velocities and equivalent widths most prominent lines are presented. built spectral energy distribution estimated main parameters for example obtained bolometric luminosity $L_{V565}\approx 130L_{\odot} $ . Considering all features we came to conclusion that this young intermediate-mass can belongs some intermediate class between T Tau HAeBe stars. Very unusual a presence strong absorption Ba II spectrum. Possible explanations on issue discussed. Hence, think unique example, help understand open questions nucleosynthesis problem

PECULIAR OUTBURST OF THE NEWLY REVEALED VARIABLE STAR V838 Mon

We present photometric and highand low-resolution spectroscopic observations of the unusual outburst of V838 Mon. The data were collected at the NAO Rozhen, Bulgaria and at the Torun Observatory, Poland. Analysis of the peculiar behavior of the spectrum of the star is given. The star’s radial velocity of +60 km/s is derived. A brief discussion concerning the nature of the object is

Orbital elements of binary systems with a chemically peculiar star

When binary systems with a chemically peculiar (CP) star are compared with normal-star binary systems, they present: a lower incidence, a deficiency of short periods, rather eccentric orbits, and companions of low mass. Unfortunately these results are based on a relatively small (∼ 50) number of CP-star binary systems with known orbital parameters and a similar analysis has not yet been carried...

HVS 7 : a chemically peculiar hyper - velocity star ⋆

Context. Hyper-velocity stars are suggested to originate from the dynamical interaction of binary stars with the supermassive black hole in the Galactic centre (GC), which accelerates one component of the binary to beyond the Galactic escape velocity. Aims. The evolutionary status and GC origin of the hyper-velocity star SDSS J113312.12+010824.9 (aka HVS 7) is constrained from a detailed study ...

A spectroscopic study of the magnetic chemically peculiar star ν Fornacis

The magnetic chemically peculiar star ν Fornacis is known to be a periodic magnetic and luminosity variable. In the framework of the Oblique Rotator Model, ν For presents a mainly dipolar magnetic field, whose symmetry axis is tilted with respect to the rotational axis, non solar abundances and a non homogeneous distribution of elements on the stellar surface. The variability period is the stel...

Multiplicity of chemically peculiar stars

Recently, with the goal to study multiplicity of chemically peculiar stars, we carried out a survey of 40 stars using diffraction limited near infrared (IR) imaging with NAOS-CONICA (NACO) at the VLT. Here, we announce the detection of 27 near IR companion candidates around 25 late B-type chemically peculiar stars exhibiting strong overabundances of the chemical elements Hg and Mn in their atmo...
