The Rossiter-McLaughlin effect of WASP-129 Ab, WASP-162b, Qatar-7b, and EPIC 219388192b. The observed data points (black) are shown with their error bars. The systemic and Keplerian orbit velocities were removed. The blue line shows the best fitting model to the data, together with 1-σ (dark grey) and 3-σ (light grey) confidence intervals. -- astro-ph.EP

Absorption lines detected toward NRAO 150. The left panel shows previous detections including the o-H2CO (11,0 − 11,1) line at 4.8 GHz and the o-c-C3H2 (11,0 − 10,1) line at 18 GHz observed at the VLA (Liszt & Lucas 1995; Liszt et al. 2012) , and the CS (2-1) (98 GHz), o-c-C3H2 (21,2 − 10,1)(85.3 GHz), CCH(1, 3/2, 2 − 0, 1/2, 1) (87.3 GHz), and HCO+ (1 − 0) (89.2 GHz) lines (Lucas & Liszt 1994; Liszt & Lucas 1995; Lucas & Liszt 1996b, 2000, 2002) observed with the PdBI. The right panel presents the new observations including the o-H2CO(21,1 − 10,2) , o-H213CO(21,1 − 10,2), and p-H2CO (20,2 − 10,1) lines, the CS(3-2), C34S(3-2) lines, and the c-C3H2 transitions listed in Table 2. All displayed spectra have been normalized by the continuum strength. Vertical offsets have been used for clarity. -- astro-ph.GA
