On the nature of veiling of classical T Tauri stars spectra in the near-IR spectral band

TL;DR

This paper demonstrates that hot accretion spots on classical T Tauri stars can explain the veiling observed in their spectra across both visible and near-infrared wavelengths.

Contribution

It introduces a model linking hot accretion spots to spectral veiling in T Tauri stars, extending understanding to near-infrared wavelengths.

Findings

Hot accretion spots cause spectral veiling in T Tauri stars.

Veiling occurs in both visible and near-infrared spectral bands.

Model explains observed spectral features without additional mechanisms.

Abstract

It is shown that the existence of a hot accretion spot on the surface of classical T Tauri stars allows to explain observed veiling of their photospheric spectrum not only in the visible but also in the near infrared spectral band.
