A Comparative Study of the Supernova Remnant Cassiopeia A from 2013--2020 Deep [Fe II]+[Si I] Images

Seung-Hoon Jung, Bon-Chul Koo, Yong-Hyun Lee +2

We present a comparative analysis of supernova remnant Cassiopeia A based on two deep, narrow-band images covering the [Fe II] 1.644um + [Si I] 1.645um lines obtained in 2013 and 2…

Cerium features in kilonova near-infrared spectra: implication from a chemically peculiar star

Masaomi Tanaka, Nanae Domoto, Wako Aoki +14

Observations of the kilonova from a neutron star merger event GW170817 opened a way to directly study r-process nucleosynthesis by neutron star mergers. It is, however, challenging…

Near-Infrared Spectroscopy of Dense Ejecta Knots in the Outer Eastern Area of the Cassiopeia A Supernova Remnant

Bon-Chul Koo, Yong-Hyun Lee, Jae-Joon Lee +1

The Cassiopeia A supernova remnant has a complex structure, manifesting the multidimensional nature of core-collapse supernova explosions. To further understand this, we carried ou…

The IGRINS YSO Survey III: Stellar parameters of pre-main sequence stars in Ophiuchus and Upper Scorpius

Ricardo López-Valdivia, Gregory N. Mace, Eunkyu Han +9

We used the Immersion GRating Infrared Spectrometer (IGRINS) to determine fundamental parameters for 61 K- and M-type young stellar objects (YSOs) located in the Ophiuchus and Uppe…

The IGRINS YSO Survey I. Stellar parameters of pre-main sequence stars in Taurus-Auriga

Ricardo López-Valdivia, Kimberly R. Sokal, Gregory N. Mace +19

We present fundamental parameters for 110 canonical K- & M-type (1.30.13) Taurus-Auriga young stellar objects (YSOs). The analysis produces a simultaneous determination…

Evidence of Accretion Burst: The Viscously Heated Inner Disk of the Embedded Protostar IRAS 16316-1540

Sung-Yong Yoon, Jeong-Eun Lee, Seokho Lee +5

Outbursts of young stellar objects occur when the mass accretion rate suddenly increases. However, such outbursts are difficult to detect for deeply embedded protostars due to thei…
