Early Spectroscopy and Dense Circumstellar Medium Interaction in SN 2023ixf

K. Azalee Bostroem, Jeniveve Pearson, Manisha Shrestha +53

We present the optical spectroscopic evolution of SN~2023ixf seen in sub-night cadence spectra from 1.18 to 14 days after explosion. We identify high-ionization emission features,…

The Early Light Curve of SN 2023bee: Constraining Type Ia Supernova Progenitors the Apian Way

Griffin Hosseinzadeh, David J. Sand, Sumit K. Sarbadhicary +39

We present very early photometric and spectroscopic observations of the Type Ia supernova (SN Ia) 2023bee, starting about 8 hr after the explosion, which reveal a strong excess in…

SN 2022acko: the First Early Far-Ultraviolet Spectra of a Type IIP Supernova

K. Azalee Bostroem, Luc Dessart, D. John Hillier +41

We present five far- and near-ultraviolet spectra of the Type II plateau supernova, SN 2022acko, obtained 5, 6, 7, 19, and 21 days after explosion, all observed with the Hubble Spa…

TOI-3714 b and TOI-3629 b: Two gas giants transiting M dwarfs confirmed with HPF and NEID

Caleb I. Cañas, Shubham Kanodia, Chad F. Bender +36

We confirm the planetary nature of two gas giants discovered by TESS to transit M dwarfs. TOI-3714 () is an M2 dwarf hosting a hot Jupiter ($M_p=0.70 \pm 0.03~\ma…

TESS first look at evolved compact pulsators: Known ZZ Ceti stars of the southern ecliptic hemisphere as seen by TESS

Zs. Bognár, S. D. Kawaler, K. J. Bell +13

Context. We present our findings on 18 formerly known ZZ Ceti stars observed by the TESS space telescope in 120s cadence mode during the survey observation of the southern ecliptic…

TESS first look at evolved compact pulsators : Discovery and asteroseismic probing of the g-mode hot B subdwarf pulsator EC 21494-7018

S. Charpinet, P. Brassard, G. Fontaine +29

We present the discovery and asteroseismic analysis of a new g-mode hot B subdwarf (sdB) pulsator, EC 21494-7018 (TIC 278659026), monitored in TESS first sector using 120-second ca…
