    Mother–child correlation of kidney function: data from the Yamanashi Adjunct Study of Japan Environment and Children’s Study (JECS)

    Individual variation in kidney function can be affected by both congenital and acquired factors, and kidney function in children is possibly correlated with that in their mothers. However, the mother–child correl...

    The renin-angiotensin system and hypertension in autosomal recessive polycystic kidney disease

    Hypertension is a well-recognized complication of autosomal recessive polycystic kidney disease (ARPKD). The renin-angiotensin system (RAS) is a key regulator of blood pressure; however, data on the RAS in ARP...

    Tycho Brahe’s 1572 supernova as a standard type Ia as revealed by its light-echo spectrum

    Type Ia supernovae, used as distance indicators by cosmologists, result from thermonuclear explosions of white dwarf stars in binary systems. Important questions remain about how the explosions proceed and the...

    Molecular Hydrogen Absorption Line Detected in Dense Molecular Clouds

    The H2 ν=0–1 S(0) absorption line was detected together with CO ν=0–2 toward NGC 7538 IRS1 using IRCS at Subaru Telescope. The H2/CO ratio are directly measured to be 5100±1700 on the assumption that H2 ortho-to-...

    Note on Spectroscopy with Adaptive Optics

    The performance of adaptive optics (AO) systems is more often discussed in the context of imaging capability. However, it is also a powerful front-end optics for a spectrograph to gain physical and chemical in...

    The Carbon Isotope Ratio in Local Molecular Clouds

    We report the carbon isotope ratio in nearby molecular clouds LkHα 101, AFGL 490, and Mon R2 IRS 3. The vibrational transition bands of 12CO ν = 2 ← 0 and 13CO ν = 1 ← 0 were observed with high resolution near-in...

    Absorption Line Survey of H+3 Towards the Galactic Center

    We have conducted high-resolution (R = 20,000) spectroscopy toward sources in the Galactic center in search of absorption lines of H+3. The observation had been so far limited to the absorption lines from the low...

    The Structure of the Young Stellar Outflows Revealed by High Angular Resolution [Fe II] λ 1.644 μ m Spectroscopy

    We introduce results of the [Fe ii] λ1.644 μm spectroscopic observations toward the outflows emanating from L1551 IRS 5, DG Tau, HL Tau, and RW Aur. We resolved the region within ~±140 AU (< ±1′′) from their driv...
