"Professor Pang, hello, I am Liu Feichi, director of the Gaogumei Observatory, and welcome to our Gaogumei station to visit and guide!"

"Stationmaster Liu, hello!"

Pang Xuelin shook hands with Liu Feichi with a smile, and then, under Liu Feichi's introduction, he shook hands with others one by one.

Some of these people work at the observatory, and some are just doctoral and master's students who come to study.

But when they saw Pang Xuelin, they were also so excited that they couldn't help themselves.

After all, the name of the person, the shadow of the tree.

Needless to say, Pang Xuelin's achievements in the academic world are also all over the real academic circle, just like those top stars in the entertainment industry.

For Liu Feichi, if an entertainment star is in front of them, they may not know each other.

But when Pang Xuelin is in front of them, they will be as excited as those brainless fans who see their idols.

Liu Feichi glanced at Yao Bingxia, who was standing aside, and said, "Professor Pang, you and your girlfriend came over together, don't leave at night, there is an expert building in our station, you can just live in it." ”

"Okay, then I'll trouble you!"

Pang Xuelin was also polite and said with a smile.

Seeing Pang Xuelin walk into the observatory surrounded by Liu Feichi and others, the accosting man frowned, walked to the door of the observatory, and asked the security guard: "Big brother, who was that young man just now, you Director Liu is so enthusiastic?" ”

The security guard himself was still confused, and said: "I don't know who he is, just now Director Liu called him Professor Pang." ”

"Professor Pang, Professor Pang ......"

The pick-up man muttered to himself, there doesn't seem to be such a character in the domestic astronomy community.

Suddenly, the accosting man's eyes widened, and he said incredulously: "Professor Pang? Could it be Pang Xuelin! ......"

The man who accosted him just now felt that the young man's face was a little familiar, and now that he made such a comparison, he immediately confirmed his guess!

At this time, the companions of the accosting man stepped forward and asked, "Lao He, who was that young man just now?" is so awesome, Director Liu actually came out of it to greet him personally! ”

The accosting man said: "We missed a big guy ......"

……

Not to mention the sensation caused by Pang Xuelin's name among those amateur astronomers, after entering the Gaogumei Observatory, Liu Feichi quickly arranged Pang Xuelin and Yao Bingxia in the expert building.

The expert building is actually similar to the hotel outside, the decoration is a little old-fashioned, but very clean.

In the evening, Liu Feichi asked the canteen to prepare a lot of delicacies for the banquet of Pang Xuelin and Yao Bingxia.

After eating, Liu Feichi took Pang Xuelin and Yao Bingxia to visit the observatory.

"Professor Pang, this is the most important observation equipment of our Lijiang Observatory, the 2.4-meter optical telescope. This telescope is a major innovative project jointly funded by the Chinese Academy of Sciences, the Ministry of Science and Technology, and YN Province. The project was established in 2000, completed in May 2007, passed the tripartite joint acceptance in early April 2008, and was put into observation, becoming the first project to start operation among the seven major astronomical science projects in China, and also becoming the most important observation equipment of the astronomical observation base in southern China. The imaging quality, resolution, pointing accuracy, tracking accuracy and degree of automation of the 2.4-meter telescope are relatively high, and the comprehensive performance is at the middle and upper level among the international telescopes of the same level. The imaging resolution, pointing accuracy, and tracking accuracy are the highest levels in China. ”

"This, It is our 1.8 meter telescope folding axis spectrometer, which is installed in the original 2.16 meter telescope folding axis spectrometer red end system after modification into the Lijiang 1.8 meter telescope Goude optical path, this spectrometer uses adjustable slits, the resolution is from 20000-50000, the spectral coverage is 570nm-1000nm, the CCD is 2K2K target surface, each pixel is 13.5um, the gain and readout of the CCD has multiple gears adjustable, and the current selection is the gain of 1.35e- /ADU, the readout noise is 7.14e-, and the limit magnitude of the 1.8-meter telescope fold-axis spectrometer is V~11.5 magnitude......"

Liu Feichi introduced Pang Xuelin and Yao Bingxia one by one.

Yao Bingxia said curiously: "Director Liu, do you activate the telescope every night to look at the stars?" ”

Liu Feichi said with a smile: "We decide whether to turn on the telescope according to the weather conditions, and it will be turned on for about 200 days a year." But Ms. Yao, you are lucky tonight, the weather conditions are very suitable for observation, we will turn on the telescope around 8 o'clock and end until 4 o'clock in the morning, and then you and Professor Pang can go to the computer room and see the picture captured by the telescope on the computer! We also have several small astronomical observation telescopes that you can use to look at the Moon, Mars, Jupiter, etc., so you can experience them later. ”

"Yes, yes!"

Yao Bingxia said happily.

Next, Pang Xuelin and Yao Bingxia visited the computer room together, and when Liu Feichi taught them how to use a small astronomical telescope to observe the stars, they began to try to operate the telescope to observe Jupiter, Mars, the moon, etc.

Pang Xuelin received some astronomical training in the Martian World and quickly got started.

Yao Bingxia had no foundation, and studied little by little under the guidance of Pang Xuelin.

Liu Feichi saw that the two were giggling and playing with the telescope, so he left with a smile.

The starry sky at night is clear and transparent, and it is intoxicating.

When the two were tired of watching, they sat side by side, wrapped in blankets and admiring the stars in the sky.

It wasn't until nearly one o'clock in the morning that Yao Bingxia yawned and went back to the expert building with Pang Xuelin to rest.

Both of them were a little tired tonight, Yao Bingxia slept on the bed, Pang Xuelin also closed his eyes, and was just about to go to bed when the voice of the system suddenly sounded in his head.

"Host, please be careful, the new plane will open in half an hour, please be ready!"

Pang Xuelin was slightly stunned, and then suddenly he came back from the world of rural teachers, and another three months had passed.

He thought about it and hurriedly woke up Yao Bingxia on the side.

"Brother Xiaolin, what's wrong? People are so sleepy! ”

Pang Xuelin said: "Xiao Xia, if I don't wake up in the next two days, just send me to the hospital for glucose and amino acids to keep the nutritional supply going, and you don't have to worry about anything else, you know?" ”

Yao Bingxia was excited, sobered up, and said with some worry: "Brother Xiaolin, what's wrong with you, nothing will happen!" ”

Pang Xuelin said with a smile: "Don't worry, it's okay, remember what I said, your task now is to sleep well." ”

Yao Bingxia smiled bitterly: "You say that, how can I still sleep." ”

Pang Xuelin patted her on the back and said, "Be good, sleep well, if you don't sleep, I'll sleep first." ”

"That'...... All right! ”

Yao Bingxia closed her eyes a little helplessly and put her head into Pang Xuelin's arms.

Pang Xuelin also closed his eyes.

Half an hour later, the system turned on the countdown: "Ten, Nine, Eight, Seven, Six, Five, Four, Three, Two, One...... Host, welcome to the world of Whale Song! ”
