The mass distribution of clumpy accretion onto the nearby young star TW Hya
Tao Ji, Javier Serna, Gregory J. Herczeg +12
The proliferation of high time-resolution and decades-long monitoring of classical T Tauri stars provides a vast opportunity to test the variability of the star-disk connections. H…
The ODYSSEUS Survey. Characterizing magnetospheric geometries and hotspot structures in T Tauri stars
Caeley V. Pittman, C. C. Espaillat, Connor E. Robinson +20
Magnetospheric accretion is a key process that shapes the inner disks of T Tauri stars, controlling mass and angular momentum evolution. It produces strong ultraviolet and optical…
A multiwavelength light curve analysis of the classical nova KT Eri: Optical contribution from a large irradiated accretion disk
Izumi Hachisu, Mariko Kato, Frederick M. Walter
KT Eri is a classical nova which went into outburst in 2009. Recent photometric analysis in quiescence indicates a relatively longer orbital period of 2.6 days, so that KT Eri coul…
JWST Detects Neon Line Variability in a Protoplanetary Disk
C. C. Espaillat, T. Thanathibodee, C. V. Pittman +6
We report the first detection of variability in the mid-infrared neon line emission of a protoplanetary disk by comparing a JWST MIRI MRS spectrum of SZ Cha taken in 2023 with a Sp…
PENELLOPE V. The magnetospheric structure and the accretion variability of the classical T Tauri star HM Lup
A. Armeni, B. Stelzer, R. A. B. Claes +9
HM Lup is a young M-type star that accretes material from a circumstellar disk through a magnetosphere. Our aim is to study the inner disk structure of HM Lup and to characterize i…
Eta Carinae's 2014.6 Spectroscopic Event: Clues to the Long-term Recovery from its Great Eruption
A. Mehner, K. Davidson, R. M. Humphreys +9
Aims. Every 5.5 years eta Car's light curve and spectrum change remarkably across all observed wavelength bands. We compare the recent spectroscopic event in mid-2014 to the events…
